    Factoring polynomials never goes away. You have to factor numerator and denominator. x^3+x^2-4x-4 can be factored "by grouping" as X^3+x^2-4x-4=(x^3-4x)+(x^2-4)+(x^2-4)=(x+1)*(x^2-4) It can be factored further because the difference of squares x^2-4=x^2-2^2 factors as (x-2)*(x+2) x^2+2x-3=(x+3)*(x-1)

    oh and the function is not defined (it does not exist) for x=1 and for x=-3 because the denominator is zero for those values of x .

    x=1 and x=-3 would result in a division by zero, and as you know that is a "no-no" and would result in a discontinuity.

    Yes, that is what the problem is seeking.

    I am not sure what occurs when x=-3 but x=3 and x=-3 is probably your best choice.

    Regarding the graph, you do have a y intercept at x=-3. It is a function as a vertical line will not intercept the y values twice. It is a non-linear function.
