Question

Let f(x) = 4x – 32 and g(x) = 4x.

Part 1 What is (f ◦ g)(x) ?
Part 2 Describe the method you used to solve this problem.

I want to double check if my answers are right, but I don't understand part 2?

Answer 1

(f ◦ g)(x) = f(g(x))
f(4x)=4(4x)-32
= 16x-32
part2:
g(x) is the x ....that means you use g(x) instead of x
i guess

Answer 2

So for the first part you are like distributing the x to f and g?

Answer 3

(f ◦ g)(x) is equivalent to f ( g(x) ) u substitute the whole g(x) instead of x in f(x)

since g(x)=4x
so f( g(x) )= f(4x) = 4(4x) - 32

Answer 4

Hehe, don't believe me eye ;)

Answer 5

Lol I do, I just want a further explanation xD

Answer 6

Ok now I understand, thank you guys so much :)
