To the right of and including x 1, the graph is given by y. Through graphing these two functions, students can see how the absolute value function has a different structure from most functions students are used to seeing. When we graph piecewise functions, we are really graphing different pieces of different lines.
I can write the equation of a piecewise definied function, given the graph.

Notes graphing inequalities monday, september 28, 2015 day 10 graphing inequalities page 74. Crucially, in most settings, there must only be a finite number of subdomains, each of which must be an interval, in order for the overall function to be called piecewise. A piecewise function is called piecewise because it acts differently on different pieces of the number line.

Given nonoverlapping intervals on the real number line, a real piecewise linear function is a function from the union of the intervals on the real number line that is defined by possibly different linear functions on each interval. Use piecewise functions to model reallife quantities, such as the amount you earn at a summer job in example 6. I can write and graph piecewise definied functions. A piecewise function is a function represented by two or more functions, each corresponding to a part of the domain. Piecewise functions are defined using the common functional notation, where the body of the function is an array of functions and associated subdomains.
