Option (a)

Work Step by Step

RECALL: The graph of a function crosses the x-axis at two different points when the function's discriminant, which is $b^2-4ac$, is positive. The discriminant of the given function is greater than zero, which is positive. Thus, the function's graph will cross the x-axis at two different points and therefore has two x-intercepts. Therefore, the answer is Option (a).
