Question

(a) All local maximum values of f: Box (b) All values at which ƒhas a local maximum :

Answer 1

- The local minimum and local maximum of a graph are the y-values of the coordinate points where the graph has a valley and a peak respectively.

- These points are depicted below:

- Thus, the local maximum value and where the function has a maximum are

`\begin{gathered} \text{ Maximum:}f=2 \\ \\ \text{ Where the function has a Maximum is: }x=-2 \end{gathered}`
