Study Notes
Understanding Logarithmic Functions
- Determining intercepts involves finding points where the graph intersects the axes: x-intercepts occur where y=0, while y-intercepts occur where x=0.
- Zeroes of a logarithmic function are values of x where the function equals zero, typically found by solving the equation log_b(x) = 0, leading to x=1.
- Asymptotes are lines that the graph approaches but never reaches; for logarithmic functions, the vertical asymptote typically occurs at x=0, indicating that the function is undefined for x ≤ 0.
Characteristics of Zeroes
- The zeroes of a logarithmic function represent the x-values that yield a function output of zero, indicating critical points in the graph.
- Zeroes can contribute to understanding the behavior of the function, particularly when analyzing intervals of increase or decrease.
Significance of Asymptotes
- Identifying asymptotes is crucial for understanding the end behavior of logarithmic functions and the limitations of the function's domain.
- Vertical asymptotes help identify where the function is undefined, guiding the overall graph shape and predicting behavior near the asymptote.
