The table below represents the velocity of a car as a function of time:
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? (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 tell what the average rate represents. (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?

Part A. y-intercept tells about how much velocity does car reaches in a certain time.

Part B. the average rate of change is = x+1,y+2

Part C. Car reaches 60 miles per hour of velocity in 5 hours.

Step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

    200 words per minute

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
