Question

State the domain and range the following function:

$g\left(x\right)=\frac{1}{x}$

Answer 1

• If $x=0$ , then $g\left(x\right)$ does not exist
• 
  
• Therefore domain if $g\left(x\right)$ is $x$ belongs to all real numbers except $0$ ($x\ne 0$)
• 
  
• The range is all real numbers except $0$
