It is 7
2 below the zero, 12 above = 14 steps
middle point is 7
I think that the median decreases, but not so sure.
Leap years have 366 days, and there are 8 pints per gallon. So we divide the 366 days by the 8 pints per 1 gallon. We end up getting:
45.75 gallons in 1 leap year.
When x is -4:
y=-3(-4)+4
y=16
-2:
y=-3(-2)+4
y=-2
0:
y=-3(0)+4
y=4
2:
y=-3x2+4
-2
Hope that helps
