Example Question #51 : Functions And Graphs
Determine the domain of the following function:
and
and
and
and
The domain is all the possible values of . To determine the domain, we need to determine what values don't work for this equation. The only value that is not allowed for this equation is 5, since that would make the denominator have a value of , and you can not divide by . Therefore, the domain of this equation is:
and
