Is it a function for the given domain

[opel]

Given that f:R-->R, where f is defined as f(x) =(x+2)/(x-1)

Is the above a function supporting the definition of function?

I'm not sure what you're asking...? Did the instructions tell you to determine whether or not a given relation (formula) is also a function? If so, what is the definition they gave you for a function? What have you done with this information? Where are you getting stuck?

When you reply, please include the full and exact text of the exercise (the above "Given" is an incomplete sentence), the instructions, and a clear listing of your thoughts and efforts so far. Thank you!

According to the title of the subforum in which you posted, the answer is no.

If it were \(\displaystyle f: \mathbb{R} \setminus\{1\}\to \mathbb{R}\) then yes.

A different answer may be more appropriate for a different level of mathematics.

Please let us know so the help is appropriate.
