Find the domain of y=x%2B3 if the range is -1,1,3,5
Substitute each value for y and solve for x.

y+=+x%2B3 ...............plug in first value -1
-1+=+x%2B3.....move 3 to the left
-1+-+3+=+x.....
-+4+=+x.....

y+=+x%2B3 ...............plug in first value 1
1+=+x%2B3.....move 3 to the left
1+-+3+=+x.....
-+2+=+x.....

y+=+x%2B3 ...............plug in first value 3
3+=+x%2B3.....move 3 to the left
3+-+3+=+x.....
0+=+x.....

y+=+x%2B3 ...............plug in first value 5
5+=+x%2B3.....move 3 to the left
5+-+3+=+x.....
2+=+x.....
so, the domain is: -4,-2,0,2
