Question

Given f(x)=x+3 and g(x)=x^2, which function represents f(g(x))?

Answer 1

\[\large \color{blue}{f(x)=x+3},\qquad\color{orangered}{ g(x)=x^2}\]
\[\huge \color{blue}{f(}\color{orangered}{g(x)}\color{blue}{)}= \color{blue}{f(}\color{orangered}{x^2}\color{blue}{)}\]

\[\huge \color{blue}{f(x)=(x)+3} \quad \rightarrow \quad\color{blue}{f(}\color{orangered}{x^2}\color{blue}{)=(\color{orangered}{x^2})+3}\]

Answer 2

Understand how I plugged that in?
Lemme know if you're still confused.

Answer 3

I do! Thanks so much!
