What is piecewise linear equation?

A piecewise linear function is a function composed of some number of linear segments defined over an equal number of intervals, usually of equal size.

What is the formula of piecewise function?

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 < x ≤ -1, and f(x) = -7 when -1.

How do you find the equation of a piecewise linear function graph?

Finding the Equation of a Piecewise Function: Find the equation for both lines y=mx+b form. If there is an O, then the equation will be > or <, if there is • the equation is ≥ or ≤. The line itself is X in the equation.
