Step 2.1

Raise $0.5$ to the power of $2$ .

$y = 0.25 + x - 3$

Step 2.2

Subtract $3$ from $0.25$ .

$y = x - 2.75$

Step 3

Choose any value for $x$ that is in the domain to plug into the equation.

Step 4

Choose $0$ to substitute in for $x$ to find the ordered pair.

Step 4.1

Remove parentheses.

$y = 0 - 2.75$

Step 4.2

Remove parentheses.

$y = (0) - 2.75$

Step 4.3

Subtract $2.75$ from $0$ .

$y = - 2.75$

Step 4.4

Use the $x$ and $y$ values to form the ordered pair.

$(0, - 2.75)$

Step 5

Choose $1$ to substitute in for $x$ to find the ordered pair.

Step 5.1

Remove parentheses.

$y = 1 - 2.75$

Step 5.2

Remove parentheses.

$y = (1) - 2.75$

Step 5.3

Subtract $2.75$ from $1$ .

$y = - 1.75$

Step 5.4

Use the $x$ and $y$ values to form the ordered pair.

$(1, - 1.75)$

Step 6

Choose $2$ to substitute in for $x$ to find the ordered pair.

Step 6.1

Remove parentheses.

$y = 2 - 2.75$

Step 6.2

Remove parentheses.

$y = (2) - 2.75$

Step 6.3

Subtract $2.75$ from $2$ .

$y = - 0.75$

Step 6.4

Use the $x$ and $y$ values to form the ordered pair.

$(2, - 0.75)$

Step 7

These are three possible solutions to the equation.

$(0, - 2.75), (1, - 1.75), (2, - 0.75)$
