A laboratory designed a radio telescope with a diameter of 380 feet and a maximum depth of 50 feet. the graph depicts a cross section of this telescope. find the equation of the parabola

Question

anonymous · Answer

Does the graph show the curve ot the telescope passing through the origin and symmetrical around the y axis?  If so then the problem is really asking you to find the value of A in $$y=Ax ^{2}$$
If you know another point on the parabola you can find this by substituting its x and y values into the equation and solving for A.
