Question

At what values of x does f(x)=0?

Answer 1

Explanation:

Look for the three dots on the x-axis: You find them at -1, 2 and 4.

At these x-values the function has zeros (roots or solutions).

Thus, the 3 correct answers are B (x = 2) and F (x = 4). -1 is also a solution, but is not listed.
