Hi, there please help me and thank you in advance

Question

1)If f(x)= 4x-8 and g(x)=-x²+6x-8

f(x)• g(x)

2) f(x)=2x³-5x²

g(x)=2x-1

Find (f•g)(x)

Answer 1

1) I assume the first one is just to multiply the two functions together.

2) Here you substitute g(x) or (2x-1) everywhere you have an x in f(x):

2(2x-1)³ - 5(2x-1)²
