Identify the monomial function described as odd or even, and indicate whether a is positive or negative. As x > 0 increases, f(x) increases. As x < 0 decreases, f(x) decreases. As x > 0 increases, f(x) decreases. As x < 0 decreases, f(x) decreases. As x > 0 increases, f(x) increases. As x < 0 decreases, f(x) increases. As x > 0 increases, f(x) decreases. As x < 0 decreases, f(x) increases.
