Question

the domain is all negative integers greater than -7,the range is x less than 5, where x is a member of the domain

Answer 1

Domain is { -6 -5 -4 -3 -2 -1 }. "x less than 5" where x∈[-6,-1] is { 11 10 9 8 7 6 }.

Range is { 11 10 9 8 7 6 } or [6,11].

-6 maps to 11 because 5-(-6)=5+6=11.

Similarly -5 maps to 10, etc.

For example: f(x)=5-x where x∈ℤ and -7<x<0.
