Answer:
(f o g) (x) = 36x² + 3
(g o f) (x) = 6x² + 18
Step-by-step explanation:
f(x) is x² + 3
g(x) is 6x
(f o g) (x) means for all xs in f replace it with g(x) or 6x
(f o g) (x) = (6x)² + 3 - see 6x is in place of x and 6x is g(x)
(f o g) (x) = 36x² + 3
(g o f) (x) = 6(x² + 3)
(g o f) (x) = 6x² + 18
Answer:
f(g(x)) = 36x^2+3
g(f(x)) = 6x^2+18
Step-by-step explanation:
f(x) =x^2+3
g(x) =6x
f°g(x) = means put g(x) in for x into the function f(x)
f(g(x)) = (g(x))^2 +3
(6x)^2 +3
36x^2+3
g°f(x) = means put f(x) in for x into the function g(x)
g(f(x)) = 6(f(x)
6(x^2+3)
6x^2+18
