Strategic Advice: When using function notation, f(x) is simply another way of saying y, so this question is asking you to find the values of x for which y = 0, or in other words, where the graph crosses the x-axis.

Getting to the Answer: The graph crosses the x-axis at the points (-2, 0) and (3, 0), so the values of x for which f(x) = 0 are -2 and 3.
