Chapter 13.6, Problem 11E

(a)

To determine

The point of intersection of the two curves $f\left(x\right)$ and $g\left(x\right)$. The graphs are following these equations:

$f\left(x\right)=\frac{x}{2}$

$g\left(x\right)=\sqrt{x}$

(b)

To determine

To calculate: Area between the curves in the interval $\left[0,4\right]$.

(c)

To determine

To calculate: Area between the curves in the interval $\left[4,9\right]$.

(d)

To determine

To calculate: Area between the curves in the interval $\left[0,9\right]$.
