In the following list identify a true statement on the function

f

.

f (x) = \frac{- 2 (3 x + 1)}{(2 x + 3) (2 - x)}

f (x) > 0 ⟺ x \in (- \frac{3}{2}; - \frac{1}{3}) \cup (2; \infty)

f (x) > 0 ⟺ x \in (- \infty; - \frac{3}{2}) \cup (- \frac{1}{3}; 2)

f (x) > 0 ⟺ x \in (- \frac{3}{2}; 2)

f (x) > 0 ⟺ x \in (- \infty; - \frac{3}{2}) \cup (2; \infty)
