Question

I NEED TO CHECK MY ANSWER! I WILL GIVE OUT A MEDAL!

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:

Answer 1

What does the x-intercept of the function for car 1 represent?

The x-intercept represents the time it takes car 1 to travel a certain distance and the domain values.

What does the y-intercept of the function for car 2 represent?

The y-intercept for car 2 represents the distance that car 2 travels.

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

The domain for car 1 and car 2 is [0, 10, 20, 30, 40].

What is the average rate of change from x = 10 to x = 30 for the function representing the motion for car 2? What does the value of this average rate of change represent?

The average rate of change for x = 10 and x = 30 for car 2 is -0.5.

Answer 2

I want to make sure that my answers are correct

Answer 3

@thomaster

Answer 4

domain for car 1 would be 0\(\le\)x\(\le\)40
for car 2 it would be 0\(\le\)x\(\le\)wherever car 2 ends

Answer 5

oh ok, but is everything else alright?

Answer 6

I would put that the y-intercept is how far away the car started.

Answer 7

ok
