How do you find the point on the parabola y=x^2 nearest the
point (-3,0)???
Thanks,

Hey there!
I'll see if I can get you started, although I'm not sure how far you've
gotten yet.
You want to use the distance formula (between the given point and a general
point on the parabola), and then minimize the quantity it gives you. So
this will be set up as a max-min problem, and you'll take the derivative of
the distance, set it equal to zero, blah blah blah.
Let us know if this isn't enough to get you going.
