Question

HELPP WILL GIVE BRAINEST!!!!!!!!!!!!!!!!!!!!!!!!!!

The table below represents the distance of a car from its destination as a function of time:


Time
(hours)
x Distance
(miles)
y
0 900
1 850
2 800
3 750

Part A: What is the y-intercept of the function, and what does this tell you about the car? (4 points)

Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 3, and tell what the average rate represents. (4 points)

Part C: What would be the domain of this function if the car traveled the same rate until it reached its destination? (2 points)

Answer 1

A: 900, the car started 900 miles from its destination.  
B: The average rate of change is 50, meaning the car goes 50 miles per hour towards its destination.  
C: The domain of the function would be 0-18 since the car reaches its destination after 18 hours.
