\(r(x)\) has domain \(\{-1,0,1,2\}\) and range \(\{0,2,4,6\}\). \(s(x)\) has domain \(\{1,2,3,4\}\) and is defined by \(s(x)=x+1\) . What is the sum of all possible values of \(s(r(x))\) ?

The outputs you can get from r(x) are: 0, 2, 4, 6.

Plugging those into s(x), we see that the only values in the domain of s(x) are 2 and 4. So your answer is s(2) + s(4) = 3 + 5 = 8.

Hope this helped!

It really did! Thanks!
