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:
It will take 2.8 minutes
Step-by-step explanation:
Given


See attachment for complete question
Required
Time to fill the tube with 46.2 gallons
The attached table is a represents a direct proportional relationship between x and y.
This relationship is:

Where k is the constant of proportionality.
When (x,y) = (1,16.5), we have:



So, we have:


To calculate the required time to fill 46.2 gallons, we make x the subject

Where
