average rate of change of work from max. height unitil it reaches the ground 4 ≥ t .
<h3>WHAT IS AVERAGE RATE ? </h3>
The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function. A method that determines the amount of change in one item divided by the corresponding amount of change in another is known as an average rate of change function.
<h3>CALCULATION</h3>
h(t)=-16t^2+144t
= 16t [ 4 - t ]
4 - t ≥ t
domain is (0,4)
t is the time , time must be positive so domain starts from zero .
