Graphing Parabolas ( finding area) Find the area of the triangle formed by the origin and the points of intersection of parabolas $y=−3x^2+20$ and $y=x^2−16$.
I tried graphing it. I could figure out what it meant when it's said formed by the origin. Please help.
Could someone also please post a picture of the two graphs using online because I don't know how to do it.


Just to illustrate the answer of kamilo9875.

In red the parabola $ y=20-3x^2$ in blue $y=x^2-16$, The triangle is $AOB$ and  $A=(-3,-7)$, so the area is $3\times 7=21$.
