1. The problem asks to fill in the sign table for intervals defined by points $-5$, $0$, $2$, and $4$ on the number line. 2. The sign table shows the sign of a function or expression in each interval between these points. 3. Given signs are: negative to the left of $-5$, positive from $-5$ to $0$, positive from $0$ to $2$, and positive from $2$ to $4$, and positive to the right of $4$. 4. This means the function changes sign at $-5$ from negative to positive and remains positive through $0$, $2$, and $4$. 5. The sign table is: | Interval | Sign | |----------------|------| | $(-\infty, -5)$ | $-$ | | $(-5, 0)$ | $+$ | | $(0, 2)$ | $+$ | | $(2, 4)$ | $+$ | | $(4, \infty)$ | $+$ | 6. The blue curve above the line indicates the function is positive in the intervals after $-5$. Final answer: The sign table is negative before $-5$ and positive on all intervals after $-5$.
