Answer:
e is a function; f is not a function
Step-by-step explanation:
All functions must pass the vertical line test. this means that the when those points are plotted, no two points are on the same vertical line. You can tell if they are on the same vertical line by their x-coordinate. If two points have the same x-coordinate, then they are on the same vertical line. This means that the if two points have the same x-coordinate in the relationship, it is not a function. In e, the x-coordinates are 0, 4, 8, and 3. In f, the x-coordinates are 0, 4, 0, and 6. In e, all the x-coordinates are different, so it is a function. In f, however, 0 is a repeated x-coordinate, so it is not a function.

Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 5, - 1 ] , thus
f(b) = f(- 1) = - (- 1)² - 4(- 1) + 6 = - 1 + 4 + 6 = 9
f(a) = f(- 5) = - (- 5)² - 4(- 5) + 6 = - 25 + 20 + 6 = 1 , then
average rate of change = [tex]\frac{9-1}{- 1-(-5)}[/tex] = [tex]\frac{8}{4}[/tex] = 2

Note: Figure is not drawn to scale.
What is the elevation in feet of the road 5 miles from the starting point?
A. 1000
B. 1250
C. 750
D. 1500
Answers
Answer:
I think the answer is 1500
Step-by-step explanation:
Elevation of the road at 5 miles from the starting point is 1250 ft.
Similarity of triangles: If two triangles are similar, their corresponding sides will be proportional.
Given in the question,
Two triangles formed by a road are ΔADE and ΔABC (As shown in the figure attached).
Since, ∠A ≅ ∠A (Reflexive property)
∠AED ≅ ∠ACB (right angles)
ΔADE ~ ΔABC (By A-A property of similarity)
In these similar triangles, corresponding sides will be proportional.
[tex]\frac{AB}{BC}=\frac{AD}{DE}[/tex]
[tex]\frac{8}{2000}=\frac{5}{DE}[/tex]
[tex]DE=\frac{5\times 2000}{8}[/tex]
[tex]=1250[/tex] miles
Therefore, elevation of the road at 5 miles from the starting point will be 1250 ft.
Option (B) will be the answer.

The probability of getting 3 in 132 times is 22.
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur.
Given that, Paul rolls a fair dice 132 times.
The probability of getting 3 in one roll is 1/6
so now it is 132 rolls
so,
= 132/6
= 22
Hence, The probability of getting 3 in 132 times is 22

Which statement correctly compares the function shown on this graph with the function y= 6x - 1? y 10 8 6 4 2 -10 8 6 4 2 -2 2 4 6 8 10 2 6
A. The function shown on the graph has a greater rate of change and a higher starting point. A
B. The function shown on the graph has a smaller rate of change and a lower starting point.
C. The function shown on the graph has a smaller rate of change, but a higher starting point.
D. The function shown on the graph has a greater rate of change and a lower starting point.
Answers
Answer:
B. The function shown on the graph has a smaller rate of change and a lower starting point.
Step-by-step explanation:
✍️The function y = 6x - 1, has:
slope (m) = 6, and
Starting point/y-intercept (b) = -1
✍️Let's find the slope (m) and the starting point (y-intercept) of the function shown on the graph:
Using the points, (0, -6) and (2, 4),
Slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 -(-6)}{2 - 0} = \frac{10}{2} = 5 [/tex]
Slope (m) = 5
The strating value is the value of y when x = 0. In order words, it is the point at which the line of the function intercepts the y-axis.
The y-axis is intercepted at y = -6.
Therefore, the starting value (b) = -6.
Therefore, the statement correctly compares the function shown on the graph above with the function y = 6x - 1 is:
B. The function shown on the graph has a smaller rate of change and a lower starting point.
Comparing their slopes, 5 is smaller than 6.
Comparing their starting points, -6 is lower than -1.

How do you get the range?
Answers
The range is -4
Answer: [-4, 8]
Step-by-step explanation:
The range is the mimimum y-value, the highest y-value.
On the graph, the lowest y-value is -4 and the highest y-value is 8. Thus, when writing in the range form, the range would by [-4, 8].
The range would be in hard brackets because the range touches exactly the points of -4 and 8. If each point had an open circle, instead of a closed point, there would be soft brackets.

Two linear functions are shown. Which function has the greater initial value?
Answers
Answer:
The answer is Function A
Step-by-step explanation:
Trust me its correct
pls mark me as brainliest
Answer:
we conclude that function A has a greater initial value.
Step-by-step explanation:
As we know that the initial value is obtained by setting x=0
so
Given the function A
From function A, it is clear that at point x=0, the value of y=8
i.e.
at x=0, y=8
Given the function B
[tex]y=3x+4[/tex]
substitute the value x=0 to get the initial value of function B
[tex]y=3x+4[/tex]
[tex]y=3(0)+4[/tex]
[tex]y=0+4[/tex]
[tex]y=4[/tex]
i.e.
at x=0, y=4
Therefore, we conclude that function A has a greater initial value.
Ashlee worked 1,944 hours last year. She earned $14 for each hour she worked. She wants to use her earnings to buy a new vehicle. Vehicle Choices Price Sedan $25,750 Convertible $27,990 SUV $29,500 She said, "Since 2,000 × 14 = $28,000, and $27,990 is less than $28,000, I know I have earned enough to buy the convertible." Use the drop-down boxes to explain whether or not Ashlee's conclusion is logical.
Answers
Answer:
See Explanation
Step-by-step explanation:
The options are missing. However, the question is still solvable.
Given
[tex]Work\ Hours = 1944[/tex]
[tex]Earnings = \$14[/tex] per hour
[tex]Estimated\ Earnings = \$28,000[/tex]
[tex]Sedan = \$25,750[/tex]
[tex]Convertible = \$27,990[/tex]
[tex]SUV = \$29,500[/tex]
First, we need to calculate her actual earnings.
This is calculated by multiplying the actual work hours (without approximation) by the earnings per hour
[tex]Total\ Earnings = 1944 * \$14[/tex]
[tex]Total\ Earnings = \$27,216[/tex]
Next, we compare this actual earnings to the amount of a Convertible
[tex]\$27216 < \$27,990[/tex]
Hence, Ashlee's conclusion is not logical because with her actual earnings, she cannot afford a Convertible
