For example, consider a simple tax system in which incomes up to $10,000 are taxed at 10, and any additional income is taxed at 20%. Tax brackets are another real-world example of piecewise functions. What is a real life example of a piecewise function? The x values (in the above example −3, 0, and 3) where the slope changes are typically called breakpoints, changepoints, threshold values or knots. Since the graph of a linear function is a line, the graph of a piecewise linear function consists of line segments and rays. What does a linear piecewise function look like?

For example, we can make a piecewise function f(x) where f(x) = -9 when -9 < x ≤ -5, f(x) = 6 when -5 < x ≤ -1, and f(x) = -7 when -1 #Piecewise function definition how to
