Answer:

Step-by-step explanation:

Given the function :

f(x) = 7x - 8

Evaluate the given values of the independent variable and simplify.

a. f(7)

b. f(x + 5)

c. f(-x)

A.) f(7)

f(7) = 7(7) - 8

= 49 - 8

= 41

B.) f(x + 5)

7(x + 5) - 8

7x + 35 - 8

7x - 27

C.) f(-x)

7(-x) - 8

-7x - 8

I think it will be d because i think that’s a good guess
