Answer
$\color{blue}{\bf{ f(x)=x^2\text{ ; } g(x)=6x-2 }}$
$\color{blue}{\bf{\text{or other equivalent functions}}}$
Work Step by Step
We are given the function $\bf{h(x)= (6x - 2)^2 }$ and are asked to find two functions ${f(x)}$ and ${g(x)}$ such that $( f \text{ }\omicron\text{ g} )(x) =h(x)$
There are many ways to do this, for example:
$\color{magenta}{f(x)=x^2}$ and $\color{lime}{g(x)=6x-2}$
$\color{lime}{(6x-2)}\color{magenta}{^2}$
$\color{blue}{\bf{ f(x)=x^2\text{ ; } g(x)=6x-2 }}$
$\color{blue}{\bf{\text{or other equivalent functions}}}$
