Get the Math and Points: Aug 2016 CC Alg I Regents #5

aug-2016-cc-alg-i-5

This is a substitution question.
For answer 1, we substitute 3 for n and see if the answer is 2
Does (3-1)^2 +3(3) = 2? and looking at the table below, what is the y value when x = 3?

For answer 2, we substitute -2 for n and see if the answer is 3
Does (-2 – 1)^2 + 3(-2) = 3?
(-3)^2 – 6 = 9 – 6
If we put this equation into Y= using x instead of n we can find the answer on the table.
What is the y value when x = -2?  Is it -15 or is it 3?
