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. A f(x) is an odd function. B f(x) is an even function. C f(x) is both odd and even. D f(x) is neither odd nor even.
