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 !

Answer:
im so sorry but i havent learned this yet sorry
Step-by-step explanation:
Pi(r)(r)(2) + pi(diameter)(height)
3.14(4)(4)(2)+ 3.14(8)(1.5)
138.16
To make the second gear aligned with the first it would have to rotate 5 times, a total of 120 seconds and/or 2 minutes will pass
So the answer is I.
