f(x) = 2x, g(x) = x + 5 find (f o g)(x), (g o f)(x), (f o f)(3) and (g o g)(3)​

Sagot :

Answer and step-by-step explanation:

Please look at the picture above for the solutions.

Substitute then simplify to solve the composition of functions.

(f o g)(x) = 2x + 10

(g o f)(x) = 2x + 5

(f o f)(3) = 12

(g o g)(3) = 13
