\[y= -x ^{2}+1\] \[y= x ^{2}\] when they are equal: \[-x ^{2} + 1 = x ^{2}\] solve for x remember +/- the sqrt

Wait what?? I'm confused.

you are given 2 equations for y when they are equal you can set the 2 expressions (in x) equal: when they are equal: \[-x ^{2}+1 = x ^{2}\] So you can find the values fro x where this is true
