The graph of $f^{\text{'}\text{'}}$ is given in the figure below.

$($Click on the graph for a larger version.$)$

Draw graphs of $f$ and $f^{\text{'}},$ assuming both go through the

origin, and use them to complete the following

statements $($enter the $x-$values as $1,x2,$ etc.$)$:

A$.f(x)$ is greatest at $x=$

B$.f(x)$ is least at $x=$

C$.f^{\text{'}}(x)$ is greatest at $x=$

D$.f^{\text{'}}(x)$ is least at $x=$

E$.f^{\text{'}\text{'}}(x)$ is greatest at $x=$

F$.f^{\text{'}\text{'}}(x)$ is least at $x=$
