Find the x-intercepts of the parabola with vertex (-1,-18) and y-intercept (0,-15).
Write your answer in this form: (X1,41),(X2,42).
If necessary, round to the nearest hundredth.

Alex drew a circle with right triangle prq inscribed in it, as shown below: the figure shows a circle with points p, q, and r on it forming an inscribed triangle. side pq is a chord through the center and angle r is a right angle. arc qr measures 80 degrees.
