Question

The table below represents the distance of a car from its destination as a function of time:
Time (hour)
x
Distance (miles)
y
0 900
1 850
2 800
3 750

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, and tell what the average rate represents. (4 points)

Part C: What would be the domain of this function if the car traveled the same rate until it reached its destination?

Answer 1

I might not be getting it right off hand, but what exactly is the function?

Answer 2

And what do you know about y-intercepts? What is the set up of how the coordinates look?

Answer 3

what's the function / equation @lauren24680

Answer 4

@amanda7414 and @Godlovesme I just edited the question. Does that help?

Answer 5

can u fill the table

Answer 6

Yes @Godlovesme On the x-axis it's: 1,2,3,4. On the y-axis it's 900,850,800,750

Answer 7

So since @lauren24680 helped with the table, @Godlovesme do you know what a y-intercept ordered pair looks like?

Answer 8

yes @amanda7414 what is the value of y when x was 0 @lauren24680

Answer 9

@Godlovesme In that case the value of y was 900

Answer 10

Ok @Godlovesme you have a x value of 0 so across form that is your y-value

Answer 11

@lauren24680 that is the y-intercept
