Answer:
a.) x²+h²+2xh-8x-8h
b.) h+2x-8
Step-by-step explanation:
A.) you just plug in x+h wherever there's an x
which means you have
(x+h)²-8(x+h)
simplify and get
x²+h²+2xh-8x-8h
we already know what f(x+h) is so we just need to subtract f(x) we have
x²+h²+2xh-8x-8h-x²+8x
simplify and get
h²+2xh-8h
Divide this by h and get
h+2x-8
