    Just confused

    Not sure what this is all about or even how to do it and if anyone have any suggestions; I would greatly appreciate it Thank you!!

    Is it possible for x = 2 to be in the Domains of the functions
    a) R(x) =
    3x
    3 5x + 6
    x + 2
    b) H(x) =
    p
    x + 1
    Explain why or why not for each function.
    What are the Domains of the functions R(x) and H(x)? If required, use inf for 1.

    I certainely could have helped you if I only could read the equations of your functions.
    Please use brackets (or better: LaTeX) to write unambiguous equations.

    This is what is confusing me because this is EXACTLY how my teacher has it written and I just don't understand it

    Come again. Your teacher wrote it like that??? Man, I'd hate to be in that class.

    Sorry

    I STRONGLY DOUBT that the teacher said to write 1 as inf. I have had some poor teachers in my day, but none so benighted as to confuse 1 and [TEX]\infty.[/TEX]
    =========================

    SORRY BUT The way I wrote it WAS EXACTLY The way she wrote it because it is online class and all I did was copy and paste the question so I know I didn't get it wrong and that is why it was so confusing!

    I try to email her but she never writes me back so I thought I would try this board for help instead

    Are you paying for this online course?
    I've seen the same complaint from other students...
