Strategic Advice: The zeros of a function are the same as its roots or solutions. Graphically, the zeros are the x-intercepts. Distinct zeros mean different values of x.
Getting to the Answer: You are looking for the graph that has four different x-intercepts, or in other words, crosses through the x-axis four times, which is the graph in (D). Note that the graphs in A and C have two distinct zeros, and the graph in B has three.
