Answer

$\color{blue}{\bf{ f(x)= x^3 \text{ ; } g(x)= 2x - 3 }}$ $\color{blue}{\bf{\text{or other equivalent functions}}}$

Work Step by Step

We are given the function $\bf{h(x)= (2x - 3)^3 }$ 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: $\color{magenta}{f(x)= x^3 }$ and $\color{lime}{g(x)= 2x - 3 }$ $\color{lime}{ (2x - 3) } \color{magenta}{ ^3 }$ $\color{blue}{\bf{ f(x)= x^3 \text{ ; } g(x)= 2x - 3 }}$ $\color{blue}{\bf{\text{or other equivalent functions}}}$
