The table below represents the velocity of a car as a function of time. Table: Time Velocity (hour) (miles/hour) x y 0 50 1 52 2 54 3 56 Part 1: What is the y-intercept of the function, and what does**We plot these data where x corresponds to the time and y corresponds to the velocity. Using the calculator, y - intercept is equal to 50. y-intercept is the y-value when x is zero. The car is accelerating. The average rate of change when x =1 to x=3 is (56-52)/(3-1) or 2 miles/hour^2. The car would reach 60 miles/hour when x=5 from the acceleration of 2. Domain is 5.**...
