Question

MEDAL..........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?

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

I need help i dont just want the answer

Answer 2

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

what does y = when x = 0 ?

Answer 3

y_ intercept of the function is 2 y=2

Answer 4

are you sure about that? read the table again

Answer 5

what is the value of y when x = 0?

Answer 6

y=50 x=0

Answer 7

@Vocaloid

Answer 8

what does that tell you ?

Answer 9

right, that means the initial velocity of the car is 50 miles/hr

Answer 10

(t , v) are the ordered pairs , yea

Answer 11

@Vocaloid so the y-intercept would be 2 because 52-50/1-0 =2/1 am i correct for part A

Answer 12

no, the y-intercept is 50 because y =50 when x = 0

Answer 13

But @Vocaloid every hour it is increasing by 2 miles

Answer 14

the y-intercept is the value of y when x = 0
