Question

What is the turning point of the graph of f(x) = |4x| + 2 ?

Answer 1

let's take a peek at |4x| expression only for now

what value for "x" makes that expression 0?

Answer 2

ummm... 0?

Answer 3

yeap that means that the VERTEX or "turning point" is at \(\large \begin{array}{llll}
|4x| + {\color{red}{ 2}}
\\ \quad \\
|4({\color{red}{ 0}})|
\\ \quad \\
({\color{red}{ 0}}, {\color{red}{ 2}})\Leftarrow \textit{vertex or "turning point"}
\end{array}\)
