Study Notes
Curve Sketching
- A curve depicts the geometric interpretation of a function, showcasing its properties visually.
- Understanding curve sketching is crucial in mathematics for tracing functions accurately.
Key Elements for Curve Sketching
- Intercepts: Identify both x-intercept (where y = 0) and y-intercept (where x = 0).
-
Asymptotes: There are three types:
- Vertical: Lines approached by the curve as it nears values leading to undefined function outputs.
- Horizontal: Indicates the behavior of the curve as x approaches infinity.
- Oblique (Slant): Slanted asymptotes occurring in some rational functions.
- Variation Table: A summary of the function's behavior, showing increases and decreases across intervals.
- Excluded Regions: Areas where the function is undefined or does not exist.
- Symmetry: Determine if the function exhibits even, odd, or neither symmetry for predictions on curve behavior.
- Range of Values: The possible outputs (y-values) for the given function.
- Turning Points/Stationary Points: Points where the curve changes direction, indicating potential maxima, minima, or inflection points.
Intercepts
- The y-intercept occurs where x = 0.
- The x-intercept is at y = 0, specifically noted as y = 6.
Asymptotes
- Types of Asymptotes: Vertical, horizontal, and oblique.
- Asymptotes represent lines that the curve approaches but does not intersect.
Conditions for Asymptotes
- Most rational functions exhibit vertical asymptotes.
- For a rational function expressed as ( f(x) = \frac{g(x)}{h(x)} ):
- Vertical asymptotes exist where ( h(x) = 0 ) has real solutions.
- If ( h(x) = 0 ) lacks real solutions, no vertical asymptote is present.
