Final answer:
To evaluate the function f(x) = 17-5x at x = x+h, substitute the expression x+h into the function in place of x.
Step-by-step explanation:
To evaluate the function f(x) = 17-5x at x = x+h, we substitute the expression x+h into the function in place of x.
So, f(x+h) = 17-5(x+h).
Simplifying further, we get f(x+h) = 17-5x-5h.
