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 evaluate …
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 when -5 < …
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 …
Absolute value & piecewise functions | Algebra 1 - 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. **Unit guides …
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 (x) like this:
