Question

Start with the graph of f(x) = 9x. Then write a function g(x) that results from the given transformation.reflect f(x) about the y-axisg(x) =

Answer 1

The transformation of function and their algebraic representation are shown below:

From it we notice that to reflect the function about the y-axis we need to change the sign of the variable, then we have:

`\begin{gathered} g(x)=9(-x) \\ g(x)=-9x \end{gathered}`

Therefore, the expression of g is:

`g(x)=-9x`
