Question

I really need help with this problem! :-)

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 hours and what does the average rate represent? (4 points)

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? (2 points)

Answer 1

this is the table

Answer 2

a) (0,50) At 0 minute the speed is 50mi/hr
b) r=2
c) (5,60)

Answer 3

The y-intercept is the value of \(y\) where \(x = 0\)

Average rate of change between points A and B can be calculated by taking the value at point B, subtracting the value at point A, and dividing by the difference B - A.

Answer 4

Could you elaborate on Part C ?
