The Gravitational force (in newtons) exerted by the Earth on the space shuttle depends on "r", the shuttles distance in km from the earths center, and is given by F=GmMer-2.
where
Me=m5.97 x 1024 mass of earth in kg
m= 1.05 x 105 mass of shuttle orbiter in kg
G= 6.67 x 10-11 gravitational constant
Re=6380 radius of earth in km
A=1000 km max altitude of orbiter
based on the info, find the domain and range of the function
thank you so much to anyone who helps me!
