  1. What is your question?

    Are you solving the first one?

    If so,....

    3√x = 6
    √x = 2

    square both sides and you are done.

    I don't know what you want done with g(x) = 2x/3

  2. thanks, but for the 2nd one i'm not really sure how that is supposed to be solved.

    Precisely my point.
    You stated a function

    g(x) = 2x/3 or
    y = 2x/3

    You can do several things with that:
    1. graph it, it will be straight line
    2. state the properties of the the resulting straight line
    3. list a set of ordered pairs that satisfy the equation, (those are solutions, there would be an infinite number of correct solutions)

    Since you did not specify what you want, I cannot help you with that part.

  4. The second one merely states what the g(x) function IS. Plug in any x and calculate the corresponding g.

    If you know g and want to know what x is, then
    x = 3g/2
