$h (x) = 4 x^{4} - 5 x^{3} + 2 x^{2} - x + 5$

Step 1

Write $h (x) = 4 x^{4} - 5 x^{3} + 2 x^{2} - x + 5$ as an equation.

$y = 4 x^{4} - 5 x^{3} + 2 x^{2} - x + 5$

Step 2

The given equation $y = 4 x^{4} - 5 x^{3} + 2 x^{2} - x + 5$ can not be written as $y = k x^{2}$ , so $y$ doesn't vary directly with $x^{2}$ .

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