Homework Statement

What I want to do is calculate the area of the colored space. As you can see in the picture the function is -0.75x^2+3 for the graph.
What I did is since the colored area reaches up to y5 and not y3 I took
2
∫(-0.75x^2+5)dx
0
-
2
∫(-0.75x^2+3)dx and then multiplied the answer by 2 to get the whole area
0
as both sides are identical. I realize now that it can't be the correct way to do it though as when I type in "-0.75x^2+5" in the graph calculator the line at the x-axis changes. I would greatly appreciate help on how to solve this.
OBS: This was a problem at a test I had a few days ago, can't imagining it going well. I won't know of the results yet but I'm just curious about this specific problem.
