The table below represents the velocity of a car as a function of time:

Question

Time
(hour)
x Velocity
(miles/hours)
y
0 50
1 52
2 54
3 56

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

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

Part C: What would be the domain of the function if the velocity of the car was measured until it reached 60 miles/hour and the car does not change motion?

Answer 1

y-intercept is where x=0.

avg rate is (56-52)/(3-1)

Looks like that would be 2 more hours. So, {0..5}

Answer 2

Thank You
