Asmoke jumper jumps from a plane that is 15001500 ft above the ground. the function h equals negative 16 t squared plus 1500h=−16t2+1500 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 930930 ft? c. what is a reasonable domain and range for the function h? a. the jumper is in free fall for nothing s if the parachute opens at 1000 ft

answer: it's d

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
