is not defined for real numbers greater than 3, which would result in imaginary values for g(s).
Hence, the domain for g(s) is "all real numbers, s ≤ 3".
Also, by definition,
`g(s)=sqrt(3-s) >= 0`
Hence, the range of g(s) is "all real numbers `g(s) ≥ 0`"
We can see in the graph that s takes no values greater than 3, and that the range is greater than or equal to `0`.
