Example: Here is another piecewise function: which looks like: What is h(−1)? x is ≤ 1, so we use h(x) = 2, soh(−1) = 2 What is h(1)? x is ≤ 1, so we use h(x) = 2, soh(1) = 2 What is h(4)?
Real World Piecewise Function Example Lesson Summary Frequently Asked Questions What are piecewise functions in math? Piecewise functions show up everywhere around the real world, most commonly when buying groceries, or medicine in pharmacies. For example, when they have sales where you can either ...
What is a piecewise function example? For example, consider the piecewise function defined by p(x) = { -x if x< 0 and x if x is greater than or equal to zero. The two intervals in this example are (-infinity, 0) and 0, infinity). Graphing y=-x first on the interval (-infinit...

A piecewise function is a function that is defined on a sequence of intervals. A common example is the absolute value, |x|={-x for x<0; 0 for x=0; x for x>0. (1) Piecewise functions are implemented in the Wolfram Language as Piecewise[{{val1, c
