Answer:
A-2, B-5, C-1, D-6, E-3, F-4
Step-by-step explanation:
The A would be the function x^3, so it would be the volume of a cube which is #2
B is probably the temperature graph, because it is warmest in the middle of the day and cooler at both ends, so that is #5
C is probably the age of an oak tree because it starts at 0, and grows linearly. #1
E is #3 because it is decreasing and so is the fuel in the tank.
F is the area of a triangle one, because that would be a quadratic function (half of a parabola)#4
D is the car wash, it doesn't start at 0 because the x-axis is the time of day. #6
