Answer 1

There isn't a range.

Explanation:

If you plug any number for s(n) you will get one or more solutions for n.

After FOILing it out, you will get `26n^3 + 47n^2 + 7n - 36`.

You can see that the sign of the first quantity (`26n^3`) is positive, and that the exponent is 3, meaning that it is odd. Therefore, once you go past the least "zero", you will continuously get closer to negative infinity moving left across the graph from that point. Once you get past the last "zero", you will continuously get closer to positive infinity moving right across the graph from that point.
