Question 288672: The equation of a mirror in a particular telscope is y = x2/780 where x is the radius and y is the depth in centimeters. Graph this equation on your own, then state whether it is parabolic, elliptical, or hyperbolic.
Super confused with this question, I really don't understand where to start from, please help me!

Since we can write as which is the form (a parabola), this means that is a parabola.

Graph it to get:

Take note that the scale of the x and y axes are not equal. I did this to show what the graph looked like. In a normal setting, you probably won't see the graph.
