From the quantic function in question 9, if Lisa took the graph of y = p(x) and applied the

following transformations to produce the new function g(x). (4 marks)

Step 1: Vertical stretch by a factor 2.

Step 2: Vertical translation one unit up.

How may zero(s) does new function g(x) have? Sketch a possible graph and explain your reasoning.


The equation from question 9 was 4 (x + 2) (x - 2) (x -2)
which is the graph of y = p (x)
