Question

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?

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.

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?

Answer 1

This is on a pretest for a unit I've never learned before so don't expect me to know what everything is.

Answer 2

PART A :
The "Y" intercept tells you that the turtle is 5 miles away from the nest.
Part B: Rate of change is 22
Part C: 22 miles per hour for (x hours) given that we started at 5 miles away ... equals 225

225 - 5 = 220

220/22 = 10 hours ..there the domain = 10

Thx

no problem
