the shape of the telescope is said to be a parabola. In this case, t<span>he general form which we will pattern our equation is y- k= 4a(x – h)^2 (h,k) or vertex = (0,0) y = 4ax^2 We substitute x = 320/2 = 160, y = 46
46 = 4a (160)^2 46 = 4a (25600) 4a = 23/12800 hence the equation is </span>y = (<span>23/12800)</span>x^2
