Give the domain and range


f(x)= -4

Guest May 21, 2017

The domain is any x-value that produces a real y-value. In this function every x-value equals -4, so the domain is all the real numbers. We represent that with this notation:


\(Domain:{\{x∈\rm I\!R\}}\)


The range is the set of all the valid outputs. In this equation, the only valid output is -4. We represent that like this:


\(Range:{\{f(x)∈\rm I\!R|f(x)=-4\}}\)


To summarize, x can be any real number, and y=-4.
