The orchard needs to produce 5000 oranges, and the function they provide that represents the average number of oranges that x number of trees must provide is:
[tex]f(x)=\frac{5000}{x}[/tex]So the Range (that is the set of y values that represent this relationship) is mathematically the set of Real numbers with y different from zero. But in reality, the average number of oranges should be a whole number, not a real number. So the closest to the Range description will be given by :
Mathematically, the set of y different from zero (0) in the Real number system (W) and Reasonable: the set of y larger (>) than zero (0) in the whole number system (W)
Because you want a whole number of oranges (not half or quarter of an orange) produced by each tree, and also a non-zero production of oranges per tree.
