What is the range of the function graphed below?
A. -∞ < y < -2
B. -∞ < y < ∞
C. -∞ < y < 2
D. -2 < y < ∞
Answers
Answer:
C
Step-by-step explanation:
The range is all the (y) values the function could have. The function's left end approaches negative infinity, while the right end approaches the asymptote of the function, y = 2.
So, the range is -∞ < y < 2. The answer is C.
I hope this helps :]
The range of the function is option (C) -∞ < y < 2 is the correct answer.
What is the range of a function?The range is the set of possible output values, which are shown on the y-axis. The range of a function, f is the set of all values f(x) , such that x is in the domain of f. Graphically speaking, the range is the set of all y such that (x,y) is a point on the graph of f .
For the given situation,
The graph shows the function that is plotted on x-y axis.
The curve of the function tends from x-axis beyond infinity.
It bends at y = 2 and moves towards y-axis beyond infinity.
Hence we can conclude that the range of the function is option (C), -∞ < y < 2 is the correct answer.

Given the function y = -5x + 4, what is the range of the function if the domain is {-2, 0, 5}?
Answers
Answer:
90 hours
Step-by-step explanation:
{14, 4, -21} is the range of the function if the domain is {-2, 0, 5}
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
To find the range of the function, we need to plug each value in the domain into the given function and see what output (y-value) we get.
When x = -2:
y = -5(-2) + 4 = 14
When x = 0:
y = -5(0) + 4 = 4
When x = 5:
y = -5(5) + 4 = -21
So the range of the function is {14, 4, -21}.

Answers
Answer: (1,3) (3, infinite)
Step-by-step explanation:
i think this is right
The graph of f(x) = 4/(x² - 2x - 3) is decreasing in the values of (-1,3) ∪ (3,∞)
What is graph?A graph can be defined as "pictorial representation or the diagram that represent a data or values in an organized manner".
According to the question,
The graph of function f(x) = 4/(x² - 2x - 3).
The values (-1,3) ∪ (3,∞) substitute in the given function
f(-1) = 4/0 = undefined
f(3)= 4/0 = undefined
f(∞)= undefined
Hence, The graph of f(x) = 4/(x² - 2x - 3) is decreasing in the values of

Suppose c(x) = x3 - 24x2 + 30,000x is the cost of manufacturing x items. Find a production level that will minimize the average cost per item of making x items.
Answers
Answer:
hence the required minimum production level is 12units
Step-by-step explanation:
Given the cost function expressed as c(x) = x^3 - 24x^2 + 30,000x
The average cost function will be c(x)/x
Dividing the cost function through by x
Average cost function = c(x)/x = x³/x - 24x²/x + 30,000x/x
Average cost function = x²-24x + 30,000
A(x) = x²-24x + 30,000
If the average cost is minimized, hence dA/dx = 0
dA/dx = 2x - 24
0 = 2x - 24
-2x = -24
Divide both sides by -2
-2x/-2 = -24/-2
x = 12
For the second deriviative
d²A/dx² = 2 which is greater than zero
Hence a production level that will minimize the average cost per item of making x items is 12
The production level that will minimize the average cost per item of making x items is x = 12
How to obtain the minimum value of a function?To find the minimum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.
Putting those values of x in the second rate of function, if results in negative output, then at that point, there is maxima. If the output is positive then its minima and if its 0, then we will have to find the third derivative (if it exists) and so on.
For this case, the function in consideration is: [tex]c(x) = x^3 - 24x^2 + 30000x[/tex]
This is cost function for x items' manufacturing.
The average cost per item would be c(x) / x
This gives us a function a(x) as:
[tex]a(x) = c(x)/x = x^2 -24x + 30000[/tex]
For finding the minimum of a(x), getting its first two derivatives as:
[tex]a'(x) = 2x - 24\\a''(x) = 2 > 0[/tex]
Equating first rate to 0,
[tex]a'(x) = 2x - 24 = 0[/tex] critical point.
Since second rate is positive, the point x = 12 is point of minima, and since only one critical point is there, it is the point on which a(x) is minimum.
Thus, the production level that will minimize the average cost per item of making x items is x = 12

A ball is thrown into the air with an upward velocity of 28ft/s. Its height h in feet after t seconds is given by the function h = -16t^2 + 28t + 8
Answers
Answer:
In bold below.
Step-by-step explanation:
Find derivative which gives the velocity:
V = h' = -32t + 28
At maxm height V = 0 so
-32t + 28 = 0
Time to reach maxm height t = -28/-32 = 0.875 seconds.
So maxm height
= -16(0.875)^2 + 28*0.875 + 8
= 20.25 ft.
