Behavior of function
Create sliders for a, p, q . Write a function whose graph has vertex (p,q) and steepness coefficient a. Construct the point D on this parabola with x-coordinate -1. Using the derivative of your function, find the equation of the tangent line to the parabola at D. Vary each of the parameters p, q, m by itself and describe the behavior of the intersection point and tangent line in each case.
