An object is dropped from a height of 1700 ft above the ground. The function h=-16t^2+1700 gives the object’s height h in feet d
uring free fall at t seconds. a. When will the object be at 1000ft above the ground?
b. When will the object be 940ft above the ground?
c. What are a reasonable domain and range for the function h?
The answer is <span>a) 1000=-16t^2+1700, implies t² = -700 /-16, and t= 6.61s b) </span><span>970= -16t^2+1700, </span><span>implies t² = -730 /-16, and t=6.75s
c) reasonable domain of h h is polynomial function, so its domain is R, (all real number) its range the inverse of h is h^-1 = sqrt (1700- t / 16), and its domain is </span> <span><span><span>1700- t / 16>=0, so t <1700, the range of h is I= ]-infinity, 1700]</span> </span> </span>
