alright so here is the problem. The parabola y=x**2+3 has two tangents which pass through the point (0,–2). One is tangent to the to the parabola at (A,A2+3) and the other at (–A,A2+3). Find (the positive number) A. i've attempted this problem several times but haven't been able to find the solution. could someone tell me step by step how i would start this problem?
