Question

A smoke jumper jumps from a plane that is 1800 ft above the ground. The function h=-16^2 + 1800 gives the jumper's height h in feet during the free fall at t seconds.

a. How long is the jumper in free fall if the parachute opens at 1000​ ft?
b. How long is the jumper in free fall if the parachute opens at 950 ft?

What is a reasonable range for the function​ h?
-1800<h<1800
0<h<1800
-10<h<10
0<h<10
All real numbers

What is a reasonable domain for the function​ h?
0<t<10
0<t<1800
-1800<t<1800
-10<t<10
All real numbers
