# Write a piecewise defined function for the graph shown

## Write the equation of the piecewise function whose graph is shown

Check with the vertical line test. A General Note: Piecewise Function A piecewise function is a function in which more than one formula is used to define the output. We plot the graphs for the different formulas on a common set of axes, making sure each formula is applied on its proper domain. For help with greatest integer functions on your calculator, Click Here! The value of the function on these intervals will be n. Determine formulas that describe how to calculate an output from an input in each interval. Please read the " Terms of Use ". Each formula has its own domain, and the domain of the function is the union of all these smaller domains. Identify the intervals for which different rules apply.

All of these definitions require the output to be greater than or equal to 0. Authored by: Mathispower4u. Provided by: OpenStax. Average rate of change: is constant on each straight line section ray of the graph. Each value corresponds to one equation in a piecewise formula. For help with greatest integer functions on your calculator, Click Here! With a domain of all real numbers and a range of values greater than or equal to 0, absolute value can be defined as the magnitude, or modulus, of a real number value regardless of sign. Solution To find the cost of using 1.
