$f (x) = x^{4} + 6 x^{3} - 5 x^{2} - 24 x + 4$

Step 1

Write $f (x) = x^{4} + 6 x^{3} - 5 x^{2} - 24 x + 4$ as an equation.

$y = x^{4} + 6 x^{3} - 5 x^{2} - 24 x + 4$

Step 2

The given equation $y = x^{4} + 6 x^{3} - 5 x^{2} - 24 x + 4$ can not be written as $y = k x^{2}$ , so $y$ doesn't vary directly with $x^{2}$ .

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