How would you solve this?

Question

 If you started with a square root function and needed to find the inverse, you would end up with a parabola. Graphically, those would never line up symmetrically. What do you have to do to fix this problem?

Answer 1

they're symmetrical about the 45 degree line or x=y,

if the square root function and quadratic functions have origin as the vertex

such as y=x^2 and x=y^2

or maybe you meant by square root function as just half of the x=y^2 quadratic?

y=x^2 and y=+sqrx? to make them symmetric make the inverse y=+ or - sqrx

or if you start with y=+sqrx make the inverse y=x^2 but restrict the domain to x>0

(assuming the vertex is the origin)
