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 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? (2 points)

For 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.

so the car is at 0? right. so that would be for part A

its telling us that the car is at a stop?

No, the y intercept is at 900.

Part A y-intercept 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) / 3-1 = 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 x-values that satisfies the function domain will be from 0 to t t is the time
