The first thing to is factor the denominator of the rational function:
to do this we'll need to find two number whose product is -3 and its sum is -2; those numbers are 1 and -3, so:
Now we can rewrite our rational function as follows:
Notice that we have a common factor (x-3) in both numerator and denominator; therefore we can cancel them:
Taking all the above into consideration we realize that x=3 is a removable discontinuity; the correct answer is the first one: there is a hole in x=3 and asymptote at x=-1.

Step-by-step explanation:
It isn't clear what is supposed to go in the various blanks. We have elected to identify the corresponding congruent parts, and name the congruent triangles. The postulate supporting the conclusion is also shown.
In most cases, corresponding parts are marked congruent. The exception is the vertical angles in figure 22.
