Question

Amelia is planning the trajectory of her next flight using the altitude and distance from Paris, France. She has determined her function to be f(x) = -4x + 102.

Based on the situation above, describe any necessary restrictions to the domain and range. Provide justification for the restrictions.

Answer 1

distance x should not be negative and if x > 102/4, altitude will be negative, si i think it should be 0<=x<=102/4

Answer 2

I'm sorry I dont understand

Answer 3

in a real scenario i am considering distance and altitude can not be negative, based on that the x value domain is calculated
and range ie f(x) >=0

Answer 4

but i am not sure if it is the answer u re looking for

Answer 5

I still dont get it :(

Answer 6

if u know the answer let me know I will try to cross verify
