The table below represents the displacement of a turtle from its nest as a function of time: Time
(hours)
x Displacement
from nest
(miles)
y
0 5
1 27
2 49
3 71
4 93
Part A: What is the y-intercept of the function, and what does this tell you about the turtle? (4 points)

Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 4 hours, and tell what the average rate represents. (4 points)

Part C: What would be the domain of the function if the turtle continued to walk at this rate until it traveled 225 miles from the nest?
