Step 1.1.4.2.1.1

Raising $0$ to any positive power yields $0$ .

$e = 0 - \frac{0}{4 \cdot 1}$

Step 1.1.4.2.1.2

Multiply $4$ by $1$ .

$e = 0 - \frac{0}{4}$

Step 1.1.4.2.1.3

Divide $0$ by $4$ .

$e = 0 - 0$

Step 1.1.4.2.1.4

Multiply $- 1$ by $0$ .

$e = 0 + 0$

Step 1.1.4.2.2

Add $0$ and $0$ .

$e = 0$

Step 1.1.5

Substitute the values of $a$ , $d$ , and $e$ into the vertex form $x^{2}$ .

$x^{2}$

Step 1.2

Set $y$ equal to the new right side.

$y = x^{2}$

Step 2

Use the vertex form, $y = a {(x - h)}^{2} + k$ , to determine the values of $a$ , $h$ , and $k$ .

$a = 1$

$h = 0$

$k = 0$

Step 3
