The height, h, of a falling object t seconds after it is dropped from a platform 300 feet above the ground is modeled by the function h(t)=300-16t2 Which expression could be used to determine the average rate at which the object falls during the first 3 seconds of its fall?

h(3) - h(0)

Step-by-step explanation:

I graphed the function on the graph below and graphed the point (3,156) to find the height of the object after 3 seconds. The average rate of falling is -144

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.
