Im guessing you meant improper. This means that the numerator is greater than the denominator. An example is 11/4
The domain is -1, 0, 1, 2, 3, 4. Hope this helps.
Not sure about the first one but the second one is option c (or -3). You just have to factor and find the solutions (so it would be -7 and 4 and then u just add them)
For question 39 the answer is c
