Integrating this with upper bounds 0, and lower bounds -8, I get 91.59

However, I am just interested in the area below y=8, since my range is only 0 to 8. How can I overcome this- its been puzzling me.

I know I'm getting this result because my y intercept is 30. but how can I get the area of the function within the domain: -8 to 0, and range: 0 to 8?
