1-5.

You should recognize this function as a semicircle with radius 4, centered at the origin.

$\text{On the graph of }g(x),\text{ shade the region }A(g,0\leq x\leq 4).\text{ Observe that this area is }\frac{1}{4}\text{ the area of a }$

$\text{ complete circle, and }\frac{1}{2}\text{ the area of the semicircle, }g(x).$
