Assume $f'$ is given by the graph below. Suppose $f$ is continuous and that $f(5)=0$.

(Click on the graph for a larger version.)

Sketch, on a sheet of work paper, an accurate graph of $f$, and use it to find each of
$f(0) =$
and
$f(7) =$

Then find the value of the integral:
$\int_0^7 f'(x)\,dx =$
(Note that you can do this in two different ways!)
