Interval notation of this problem: Find the domain of the function: b) g(x)= 1/(x^2-x) I know that x can't equal to 1 or 0, but I can't figure out how write the notation.

    Yup! You set the bottom part of the fraction equal to zero right?

    In "Interval Notation" we just write the beginning and ending numbers of the interval, and use: [ ] a square bracket when we want to include the end value, or ( ) a round bracket when we don't

    Interval notation has to do with graphing can you graph this?

    hmmm... it would equal x<0 or x>10 or 0<x<10 but I'm not sure how to write the notation

    Ok so if the side with the zero is open it is represented with a ( right?

    oh the zero would be open and the 10 is closed

    And if the side with the ten is closed than it would be represented with a ] right?
