The graph shows the height h, in feet, of s football at time t, in seconds, from the moment it was kicked at ground level.

We are supposed to find the average rate of change in height from t=1.5 seconds to t=1.75 seconds.

Average rate of change in height= $\frac{\text{Change in Height}}{\text{Time taken}}\\$

As we can see from the the change in distance for the time interval 1.5 second to 1.75 second= $12-7=5$

and time= $1.75-1.5=0.25$

Average rate of change in height= $\frac{5}{0.25}\\$ =20ft/sec

Hence Required Rate of change is -20 ft/sec, because its falling(In the direction of negative y-aixs)
