Previously we learned that you can evaluate the limit of a function when a function is continuous and therefore defined at the point you. By finding the overall Degree of the Function we can find out whether the functions limit is 0 Infinity -Infinity or easily calculated from the coefficients. So you are correct that this denominator still tends to 0 for t 0.

Now you can simplify by dividing numerator and denominator by the common factor t. From the definition of continuity. The x-3 terms cancel so the function.
