Chapter 2.2, Problem 12E

In Exercises $7-12$, sketch the graph of a function that has the properties described.

$f(x)$ defined only for $x\ge 0$, $(0,0)$ and $(5,6)$ are on the graph; $f\text{'}(x)>0$ for $x\ge 0$; $f\text{'}\text{'}(x)<0$ for $x<5$, $f\text{'}\text{'}(5)=0$, $f\text{'}\text{'}(x)>0$ for $x>5$.
