Introduction to piecewise functions - Khan Academy
A piecewise function is a function built from pieces of different functions over different intervals. For example, we can make a piecewise function f (x) where f (x) = -9 when -9 < x ≤ -5, f (x) = 6 …
Worked example: graphing piecewise functions - Khan Academy
A piecewise function is a function that is defined in separate "pieces" or intervals. For each region or interval, the function may have a different equation or rule that describes it. We can graph a …
Limits of piecewise functions (video) | Khan Academy
We learn that to find one-sided and two-sided limits, we need to consider the function definition for the specific interval we're approaching and substitute the value of x accordingly.
Differentiability at a point: algebraic (function is differentiable)
We examine a piecewise function to determine its continuity and differentiability at an edge point. By analyzing left and right hand limits, we establish continuity.
Limits and continuity | Calculus 1 | Math | Khan Academy
Practice Limits by direct substitution Get 3 of 4 questions to level up! Direct substitution with limits that don't exist Get 3 of 4 questions to level up! Limits of trigonometric functions Get 3 of 4 …
Absolute value & piecewise functions - Math | Khan Academy
Piecewise functions piece together different functions. Absolute value graphs make a V shape, but why do they do that? Let's explore how to make some new and interesting types of graphs. …
Removing discontinuities (factoring) (video) | Khan Academy
Discover how to make a function continuous by determining the appropriate value for a discontinuous point. In this example, we explore the function f (x) = (6x² + 18x + 12) / (x² - 4) …
Limits and continuity | AP®︎/College Calculus AB - Khan Academy
Continuity requires that the behavior of a function around a point matches the function's value at that point. These simple yet powerful ideas play a major role in all of calculus.
Worked example: domain & range of piecewise linear functions
Finding the domain and range of a piecewise function where each segment is linear.
