Question
### Exercise: Logarithmic Function Analysis Given the function \( f(x) = -\log_2(x + 1) - 2 \), complete the following tasks: #### a) Determine the parent function and sketch its graph. Parent Function: The parent function of \( f(x) = -\log_2(x + 1) - 2 \) is \( \log_2(x) \). - **Graph Explanation:** - The graph is a standard Cartesian coordinate system with the x-axis labeled from -10 to 10 and the y-axis labeled from -10 to 10. - The scale is uniform, with grid lines at every unit on both axes. - The graph should depict a transformation of the logarithmic function, involving reflection over the x-axis, a shift to the left by 1 unit, and a downward shift by 2 units. #### b) Find the x-intercept of \( f(x) \). - **X-Intercept:** Solve \( f(x) = 0 \) to find \( x \). #### c) Find the y-intercept of \( f(x) \). - **Y-Intercept:** Evaluate \( f(0) \). #### d) Is there a vertical asymptote? If so, what is it? - **Vertical Asymptote:** There is a vertical asymptote at \( x = -1 \) due to the transformation \( (x + 1) \). #### e) Is there a horizontal asymptote? If so, what is it? - **Horizontal Asymptote:** Analyze the function as \( x \to \infty \). Note that each task should be completed with detailed calculations and graphing as needed to facilitate understanding.

**Educational Website Content:** ### Exercise on Function and Graph Analysis #### Part f: Sketching the Graph of \( f(x) \) - **Task**: Sketch the graph of \( f(x) \). Make sure to label all intercepts and asymptotes. - **Graph Details**: - The graph is plotted on a standard coordinate plane. - The x-axis and y-axis are labeled from -10 to 10. - Each axis is divided into increments of 2. - **Instructions**: 1. Identify and label the x-intercepts and y-intercepts on the graph. 2. Determine any vertical or horizontal asymptotes and mark them clearly. #### Part g: Analyzing Domain and Range - **Task**: Find the domain and range of \( f(x) \). - **Instructions**: 1. Determine the set of all possible x-values (domain) for which the function \( f(x) \) is defined. 2. Identify the set of all possible y-values (range) that the function can take. ### Tips for Solution: - Review the characteristics of the function \( f(x) \) to determine intercepts and asymptotes. - Use the graph to visually verify the intercepts and asymptotic behavior. - Apply the definition of domain and range in the context of the graph and the function's equation (if provided). Use these guidelines to complete the exercise and deepen your understanding of graphing functions and analyzing their properties.
