Answer:
<u>
</u>
Step-by-step explanation:
For the standard form equation to model the values in the table, each value of x in the table should give the matching the y value when substituted into the equation. We will test each equation:
<u>
for (-2,4)</u>

This does not give 4 as the answer and is not a solution.
<u>
for (-2,4)</u>

This does give 4 as the answer and is a possible solution.
<u>
for (-2,4)</u>

This does not give 4 as the answer and is not a solution.
<u>
for (-2,4)</u>

This does not give 4 as the answer and is not a solution.
The only possible solution is <u>
