1. The problem involves evaluating the function $g(x)$ at specific points and understanding the range of $g$. 2. Part A states the range is $(-\infty, 4]$. This means $g(x)$ can take any value less than or equal to 4. 3. Part B says the range is undefined, which means no specific range is given or it cannot be determined. 4. Part (b) asks to use the formula to evaluate $g(-1)$ and $g(1)$. 5. Given: $g(-1) = 3$ and $g(1) = 3$. 6. Part (c) asks to use the graph to evaluate $g(-1)$ and $g(1)$, but the graph is not visible, so these values cannot be determined from the graph. Final answers: - $g(-1) = 3$ (from formula) - $g(1) = 3$ (from formula) - $g(-1)$ from graph: undefined - $g(1)$ from graph: undefined
