Asking this again because I didn't get everything in the last question. My bad.

Question

Consider the function f(x)=−7x−8 and find the following:

The average rate of change between the points (x,f(x)) and (x+h,f(x+h))

There we go. Forgot I had to paste as plain text.

Answer 1

don’t forget to distribute the -7 to the x and the h when substituting the (x+h) in for the x

-7(x+h)-8-(-7x-8). -7x-7h-8+7x+8

———————— =. ———————

x + h - x. h

-7h

= ———— = -7

h
