Step-by-step explanation:
the domain is the set or range of valid values for x.
the range is the set or range of valid values for y (= f(x)).
if you did not miss anything in your problem statement, then I see a function
y = 2x - 11 + 2
no restrictions are defined.
so, domain and range are both the interval
(-infinity, +infinity).
notice the round brackets, as "infinity" is never a value and cannot be included in an interval.
now, if you missed a division sign and the function looks like
y = 2/x - 11 + 2
then we know, x must never be 0, as a division by 0 is undefined.
so, the domain in that case would be
-infinity < x < 0, 0 < x < +infinity
or short
x <> 0
the range would still be every possible value in
(-infinity, +infinity).
what is the answer for f+f
Both f's would be equal to 1 so 2
Answer:
it depends.
Step-by-step explanation:
we have to know what f means to be able to answer this question
A survey of 300 randomly selected high school students determined that 16 play organized sports.
What is the probability that a randomly selected high school student plays organized sports?
(Round to the nearest thousandth as needed.)
(a) The probability that randomly selected high school student plays organized sport is 236/300 = 59/75 = 0.787 = 78.7%.
(b) The probability means that for every 75 random students selected, 59 of them plays organized sport.

x= hamburgers
2x= cheeseburgers
x+2x=231
3x=231
x=77

Given that the range of the numbers is 67, work out 2 values of
x
.
9514 1404 393
Answer:
x = -19 or 72
Step-by-step explanation:
The range of the given numbers is 5 to 48. In order for x to make the range be 67, the value of x must be 67 less than 48, or must be 67 greater than 5.
x is 48 -67 = -19
or
x is 5 +67 = 72

A parabola can be drawn given a focus of (8,4) and a directrix of x = 6. Write the
equation of the parabola in any form.
9514 1404 393
Answer:
x = 1/4(y -4)² +7
Step-by-step explanation:
A parabola can have the equation ...
x = 1/(4p)(y -k)² +h
where the vertex is (h, k), and the vertex-to-focus distance is p.
The vertex is halfway between the focus and directrix, so has coordinates ...
((8, 4) +(6, 4))/2 = (7, 4)
The distance from the vertex to the focus is 8-7 = 1, so the equation can be written ...
x = 1/4(y -4)² +7

What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Harry filled the 75 L gas tank of his pickup truck for $73.88.
Therefore, The cost of 1L of gas is $(73.88/75) = $0.98 per liter.
And Stan paid $0.95 per liter, So Stan paid less per liter of fuel.

According to a study, 15 out of 50 adults have allergies. What percentage of adults do not have allergies?
Answer:
70% of adults do not have allergies.
Step-by-step explanation:
It states that 35 out of 50 adults do not have allergies. If we turn this into a fraction (35/50), we can then multiply the denominator by 2 to make it 100. We would then also multiply the numerator by 2.
35 x 2 =70
70/100 = .7
.7 is just the decimal form of 70%
A 48 cm wire is to cut into two pieces. One piece must be cut 10 com longer than the shorter piece. How long should each peice be?
Step-by-step explanation:
short - S
long - L
L=10+S
L+S = 48
SINCE L=10+S
10+S+S=48
10+2S=48
2S=48-10
S=38/2=19
SHORT=19CM
LONG=10+S=10+19=39CM
