Paul works at a car wash company. The function f(x) = 10 + 15.5 models his total daily pay when he washes 'x' cars. He can wash up to 15 cars each day. What is the range of this function? A) 0 ≤ x ≤ 225
A) 0 ≤ f(x) ≤ 225
A) 25 ≤ x ≤ 225
A) 25 ≤ f(x) ≤ 225

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
