If you have a scientific calculator, you can go to tables and plug each one in. whichever table has an equation matching the one provided is the answer... but if you dont have a calculator you can put in one of the x for each table and replace it in the equation then see if it matches with its corresponding y

Hello!

You can put in the x values and see if you get y

y = (-2)^2 - 2(-2) + 3

y = 4 + 4 + 3

y = 11

The only choice with this D

The answer is D where x is -2 and y is 11

Hope this helps!
