Using the graph of $g(x)$ below, answer the following questions.

1. Where is $g(x) > 0$ ? interval
2. Where is $g(x) < 0$ ?
3. Where is $g(x) = 0$ ? (List all $x$-values where $g$ is zero. Separate multiple values with commas.)
4. Where is $g'(x) > 0$ ?
5. Where is $g'(x) < 0$ ?
6. Where is $g'(x) = 0$ ? (List all $x$-values where $g'$ is zero. Separate multiple values with commas.)
