Ok, I am having a heck of a time trying to solve this one. I know that there is something to do with absolute values but not sure where I would use it. Also, do you need to graph the equation first or just set x=0? I just keep getting the wrong answer no matter how many times I have attempted to do this. Please help!

Use a definite integral to find the area between f(x)= -3+2x^2 and the x-axis over the interval [-8,1]
