Question

PLEASE HELP WILL MEDALE <3 :)

the graph below shows the distance (y) in kilometers of two cars from their destination at different times (x) in minutes. The table shows the values plotted on the graph:
Time
(in minutes)
x 0 10 20 30 40 50 60
------------------------------------------
Car 1
(in km)
y 60 50 40 30 20 10 0
------------------------------------------
Car 2
(in km)
y 60 49.02438 40.05648 32.72904 26.742 21.8502 17.85318
------------------------------------------

Answer 1

Part A: What does the x-intercept of the function for car 1 represent? (2 points)

Part B: What does the y-intercept of the function for car 2 represent? (2 points)

Part C: What is the domain of the functions for car 1 and car 2? (2 points)

Part D: What is the average rate of change from x = 20 to x = 30 for the function representing the motion for car 2? What does the value of this average rate of change represent? (4 points)
