Study Notes
Types of Discontinuities
- Infinite Discontinuity: Occurs when a function approaches infinity at a certain point; classified as non-removable.
- Point Discontinuity: A removable discontinuity where the function has a hole; can be defined at that point but is not originally included.
- Jump Discontinuity: Occurs when a function has different limits from the left and right at a certain point; classified as non-removable.
Classifications and Examples
- At x = -3: Infinite discontinuity (non-removable), signifies a vertical asymptote.
- At x = -2: Point discontinuity (removable) and at x = 3 there is an infinite discontinuity (non-removable).
- At x = -1: Infinite discontinuity (non-removable), while at x = -3 there is also a point discontinuity (removable).
- At x = 0: Infinite discontinuity (non-removable).
- At x = 5: Point discontinuity (removable).
Continuous Functions
- Certain conditions indicate the function is continuous everywhere, signifying no discontinuities present.
- Several instances designated "everywhere continuous" indicate that the function does not have any points of discontinuity.
Further Discontinuities
- Jump Discontinuities: Identified at specific points such as x = 2 and x = 4; these are non-removable.
- Point discontinuities are also found at locations such as x = 4 and x = 1, both are removable.
Summary of Context
- Understanding the nature of discontinuities is crucial for analyzing functions in calculus.
- Discontinuities impact the behavior of functions, especially in limits and continuity assessments.
