Question

Find the minimum distance from the parabola
x−y^2=0
to the point {(0,3)}.

Recall, the distance from point (x1,y1) to point (x,y) is
Sqrt[(x−x1)^2+(y−y1)^2]

Answer 1

I know the answer is 2.236
I got the the point
f'(x)=4y^3+2y-6
oh i set that equal to o but how does this tell me the answer???
pleas please help
