Does the curve y=x^2 have two different tangents which are perpendicular? Does the curve y=x^3?

3. The attempt at a solution

I have no idea how to prove that for x^2 or x^3.

(x^2)' =2x that is tangent at a point x

then m = -1/2 x for another point....

How do i prove that there is sucha point? then how about x^3?
