1. The problem involves understanding the given discrete function with domain $D = \{0,4\}$ and range $R = \{-2,2\}$. We are asked to analyze or interpret this function based on the points provided. 2. The domain $D$ represents the set of input values for the function, which are $0$ and $4$. 3. The range $R$ represents the set of output values, which are $-2$ and $2$. 4. Since the function is discrete (not continuous), it only has values at specific points, here at $x=0$ and $x=4$. 5. The points given are $(0,4)$ and $(-2,2)$, but these do not match the domain and range sets exactly. Likely, the points represent the function values: for example, at $x=0$, $f(0)=4$; at $x=-2$, $f(-2)=2$. 6. To work with this function, identify the input-output pairs clearly. For example, if the domain is $\{0,4\}$, then the function values should be $f(0)$ and $f(4)$. 7. If the points are $(0,4)$ and $(-2,2)$, then the domain is $\{0,-2\}$ and range is $\{4,2\}$, which conflicts with the sets given. 8. Clarify the domain and range from the points or vice versa. If the domain is $\{0,4\}$, then the points should be $(0,y_1)$ and $(4,y_2)$. 9. To proceed, match each domain value with its corresponding range value to form function pairs. 10. Once pairs are established, you can analyze or graph the function accordingly. Final answer: To work with the discrete function, identify the input-output pairs from the domain and range sets and plot or analyze these points accordingly.
