$h (x) = \frac{- 4 x^{2}}{(x - 3) (x + 1)}$

Step 1

Write $h (x) = \frac{- 4 x^{2}}{(x - 3) (x + 1)}$ as an equation.

$y = \frac{- 4 x^{2}}{(x - 3) (x + 1)}$

Step 2

Move the negative in front of the fraction.

$y = - \frac{4 x^{2}}{(x - 3) (x + 1)}$

Step 3

The given equation $y = - \frac{4 x^{2}}{(x - 3) (x + 1)}$ can not be written as $y = k x^{2}$ , so $y$ doesn't vary directly with $x^{2}$ .

$y$ doesn't vary directly with $x$
