medal, fan.
The table below represents the distance of a car from its destination as a function of time:
Time
(hours)
x Distance
(miles)
y
0 900
1 850
2 800
3 750
Part A: What is the yintercept 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? (2 points)

Best ResponseYou've already chosen the best response.1For part A, the y intercept is when y is equal to zero. If you look at your data, you already have the y intercept value.

Best ResponseYou've already chosen the best response.0so the car is at 0? right. so that would be for part A

Best ResponseYou've already chosen the best response.0Part A yintercept the value of y when x = 0 read Part B average rate of change of the function = slope = change in y divided by change in x f(3) f(1) / 31 = what does change in distance / time represent? Part C what is the value of t when y = 0 how long does it take to get to the destination? the domain is the set of xvalues that satisfies the function domain will be from 0 to t t is the time
