Question

Let f(x) = 5x – 26 and g(x) = 6x. What is (f ◦ g)(x) ?
please describe the method you used to solve this problem.

Answer 1

(f ◦ g)(x) means f(g(x))

Answer 2

f(x) = 5x – 26

f(g(x)) = 5*( g(x) ) – 26 ... replace each x with g(x)

f(g(x)) = 5*( 6x ) – 26 ... replace each g(x) on the right side with 6x

now simplify
