The function f(x) is shown on the graph. On a coordinate plane, a curved line shaped like a w, labeled f of x, crosses the x-axis at (negative 2, 0), (negative 1, 0), crosses the y-axis at (0, 12), and crosses the x-axis at (2, 0) and (3, 0).

What is f(0)?

12 only
2 and 3 only
–2, –1, 1, and 2 only
–2, –1, 1, 2 and 12
