Worked example: evaluating 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 …

Absolute value & piecewise functions: FAQ - Khan Academy
What are piecewise functions? Piecewise functions are functions that are defined in separate "pieces" for different intervals of the input. For example, we could define a piecewise function f …
Worked example: domain & range of piecewise linear functions
Finding the domain and range of a piecewise function where each segment is linear.
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: domain & range of step function - Khan Academy
Finding the domain and range of a piecewise function that is constant in each segment. Such functions are called "step functions."

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.
