Y = a (x + 3)² - 1
Let's take the point (-1;3)
3 = a ( -1 + 3)² - 1
3 = 4a - 1
4a = 4
Therefore a = 4/4 = 1
(x+3)² - 1
= x² + 6x + 9 - 1
= x² + 6x + 8
The answer would be y = x² + 6x + 8.
Hope this helps !

Combine like terms. 3w-3w=0. 8+2-8=2. So the answer is 2. I hope this helps!
You would need to cross multiply. When you do that you get x^2-7x-8x+56. Once simplifying you get x^2-15x+56.
