$y = \sqrt{5} x^{2}$

Step 1

Since the equation can be written in the form $y = k x^{2}$ , $y$ varies directly with $x^{2}$ and $k$ . The constant of variation, $k$ , is $\sqrt{5}$ .

$\sqrt{5}$

Step 2

The result can be shown in multiple forms.

Exact Form:

$\sqrt{5}$

Decimal Form:

$2.23606797 \dots$
