Answer:

Just mark the x intercepts

  • (-1,0)
  • (2,0)
  • (4,0)

So the zeros are

  • -1
  • 2
  • 4

Answer:

C) 4

D) 2

Explanation:

f(x) = 0 means at what value of x does y = 0 on the curve?

i.e. what are the x-coordinates of the points at which the curve intersects the x-axis?

From inspection of the graph, we can see that the curve intersects the x-axis at (-1, 0), (2, 0) and (4, 0)

Therefore, the values of x at these points are -1, 2, and 4.

So the solution to the question is C and D.
