Word Bank: increasing, decreasing, even, odd, invertible

Find the identification(s) of each of these functions. If there is none, put "Null" and if there are multiple, put the first letter of their identification along with the rest. (e.g. $f(x) = \sqrt{x-5}$ is both increasing and invertible, so you would put II for that matter.)

(1): $f(x) = \frac{x}{x^2+1}$

(2): $f(x) = x + 1 + \frac{1}{x}$

(3): $f(x) = |x| \cdot \sqrt{x}$
