Answer:

1) {3,2}

2) {8,11}

3) {-6,-5}

4) I see no match! (x+5)*2 has a range of {12,14}

Step-by-step explanation:

you substitute x with the first number of the domain (1) and you get the related range limit

then you should do the same with the other limit of the domain (2) and you get the other limit
