The question is asking for the zeros of a function, which are the values of the variable that make the function equal to zero. To find the zeros, we need to set the function equal to zero and solve for the variable. Without knowing the function, we cannot solve for the zeros exactly, but we can estimate them using a graph or a table of values. The answer choices give us several possible sets of zeros. We can test them by plugging them into the function and verifying that they make it equal to zero. Option A gives us two values, -2.17 and -7.83, which are sufficiently far apart from each other to suggest the function may cross the x-axis twice. We should choose A as the answer because it is the only option that meets this criterion.
