Final answer:

The value of x that makes f(x)=57 is x = 8.

Step-by-step explanation:

To find the value of x that makes f(x) = 57 for the function f(x) = 8x – 7, we can set the equation equal to 57 and solve for x.

8x – 7 = 57

Adding 7 to both sides, we get:

8x = 64

Dividing both sides by 8, we get:

x = 8
