Question

What is the Range and Domain of f(x)=x-7

Answer 1

Domain: All real number    Range: set of one value which is 7

Answer 2

Domain is the set of points\values that related to the independent variable (x) which make the function\equation defined!

so the domain is all the real numbers

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

so the range is also the whole real numbers






hope that helps
