1. The problem is to analyze the sign (positive, negative, or zero) of six different graphs or functions. 2. To determine the sign of a function, we look at the values of the function $f(x)$ for different $x$ values: - If $f(x) > 0$, the function is positive at that point. - If $f(x) < 0$, the function is negative at that point. - If $f(x) = 0$, the function is zero at that point. 3. Since the specific functions or graphs are not provided, I cannot analyze their signs directly. 4. Please provide the explicit functions or equations of the six graphs so I can determine where they are positive, negative, or zero. 5. Once the functions are given, I will: - Find the zeros by solving $f(x) = 0$. - Determine intervals where $f(x)$ is positive or negative by testing points between zeros. 6. This method helps understand the behavior of each graph in terms of sign. Please provide the six functions to proceed with the analysis.
