Question

1. Area of the region between the graph of y=2x^2-3x and the x -axis from x=-3 to x=1 is
a)62/3
b)97/3
c)16/3
d)20/3
e)92/3
I got e but it's incorrect

Answer 1

I also got (e).

However, that is an algebraic area, which includes the sign.

If you want the geometric area, you have to split into two parts, because it crosses the x-axis at x=0.

Answer 2

Then you get 97/3

Answer 3

I agree with Steve, it is 97/3

Answer 4

Thank you!
