(a) Find the slope of the tangent line to the parabola y = 4x - x² at the point (1, 3) (i) using Definition 1 (ii) using Equation 2

(b) Find an equation of the tangent line in part (a).

(c) Graph the parabola and the tangent line.

As a check on your work, zoom in toward the point (1, 3) until the parabola and the tangent line are indistinguishable.​
