Question

F(x) = x + 1, and g(x) = 2x.
then
g(f(x)) = [? ]x+[?]

Answer 1

this is a very interesting question

Answer 2

Answer: 2x + 2

Explanation:

The composition of two functions f and g, denoted g(f(x)), is a new function that is obtained by substituting the function f(x) into the function g(x) in place of x.

In this case, f(x) = x + 1 and g(x) = 2x. Substituting f(x) into g(x) in place of x gives us g(f(x)) = 2(x + 1) = 2x + 2.

Therefore, the final expression for g(f(x)) is 2x + 2. The coefficient of x is 2, and the constant term is 2.
