Which phrase best describes f(x), graphed on the coordinate plane below?

On a coordinate plane, a curve goes through two cycles. The first part of the curve approaches x = negative 6, has a maximum at (negative 4, 3), and has a minimum at (negative 2, negative 2). The second part of the curve has a maximum at (1.5, 2.5), has a minimum at (4, negative 3), and approaches x = 6.
f(x) is an odd function.
f(x) is an even function.
f(x) is both odd and even.
f(x) is neither odd nor even.
