Question

Medals!!!!!!!!!!!
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. Graphs of y is equal to 60 minus x and y is equal to 60 multiplied by 0.98 to the power of x
Time
(in minutes)
x 0, 10, 20, 30, 40, 50, 60
Car 1
y 60, 50, 40, 30, 20, 10, 0
Car 2
y 60, 49.02438, 40.05648, 32.72904, 26.742, 21.8502, 17.85318
Part A: What does the x-intercept of the function for car 1 represent?
Part B: What does the y-intercept of the function for car 2 represent?

Answer 1

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

Answer 2

I´m Stupid ,I can not answer this...hahaha

Answer 3

The x - intercept represents arrival at the destination.
The y-intercept is the starting distance from the destination.
