Picture shown!
If f(x) = x + 1, and g(x) = 2x,
then
f(g(x)) = [ ? ]x + [ ?]

Answer:
2x+1
Step-by-step explanation:
f(x) = x + 1
g(x) = 2x
f(g(x)) = Replace x in the function f(x) with the function g(x)
f(g(x)) = g(x) +1
= 2x+1
Answer:
f(g(x)) = 2x + 1
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(2x)
= 2x + 1
