    How do you find the domain of functions algebraically?

    ex (3x-1)/(x+3)(x-1)

    The domain of values for which this function will have a solution is simply all values except the ones that cause division by zero. So for this example if x = -3 or x = 1 there would be division by zero.

    So the domain is all real values except x = 1 or x = -3.

    Thanks
    Matt
