Question:
a. On a copy of grid to the right, sketch the graph of y = |(x - 2) (x + 3)| for -5 ≤ x ≤ 4, and state the coordinates of the points where the curve meets the coordinate axes.
b. Find the coordinate of the stationary point on the curve y = |(x - 2) (x + 3)|.
c. Given that k is a positive constant, state the set of values of k for which |(x - 2) (x + 3)| = k has 2 solutions only.
