#### Explanation:

I graphed the two functions and also roughly highlighted the area we are trying to calculate:

**Overview:** Find the integral from zero to first intersection point of the two functions of the upper function minus the lower function

**To find intersection point:** set two equations equal to each other and solve using calculator ():

(On TI 83 to TI 84+CE: either use Numerical solver under MATH menu, or graph the functions and use intersect under CALC menu)

**Area of **

Plug this into graphing calculator to get:
