Step 4: Calculating the Area

Now that we integrated the function, we want to find the area between two numbers, x=0 and x=2. 

Simply plug in the number on top (x=2) into x. Do the same with the lower number (x=0), and find the difference. 

The area, 8/3, is the total area under the function y=x^2 between x=0 and x=2.
