Question

Can someone PLEASE help me fill this chart? I’m not sure how to even get the -5?

Answer 1

See below

Explanation:

This is very easy once you understand what to do kiddo. They give you a x term, in this case -2, all you have to do is plug in this value into the equation y = x² -2x -3 which will give you your y value in this case +5 not - 5.

Heres the extra work

`y = x^2 - 2x -3\\y = (-2)^2 -2(-2) -3\\y = 4 + 4 -3\\y = 5`
