Question

The function h(t)=-4.87t^2+18.75t is used to model the height of an object projected in the air, where h(t) is the height in meters and t is the time in seconds. Rounded to the nearest hundredth, what are the domain and range of the function h(t)?

Answer 1

The correct answer is the first choice.

For the domain, we are looking at the included x-values. The values go from 0 to about 3.85.

For the range, we are looking at the included y-values. The values go from 0 to the top height of about 18.05.
