Define f(x) to be the larger of x and 2-x . Sketch the graph of f(x) . What are its domain and r

step 1 So we need to do this question first we need to grab the function x and 2 minus x so let me do h

Define f(x) to be the larger of x and 2-x . Sketch the graph...

Key Concepts

Piecewise Functions

Piecewise functions are functions defined by different expressions over different parts of their domains. They allow one to fully characterize a function that behaves differently depending on the input value. In many cases, functions defined as the maximum or minimum of other functions can naturally be expressed in a piecewise form.

Maximum Function

A maximum function outputs the larger of two or more functions or expressions for each input value. This concept is often used in optimization and in defining functions that change their form based on which of the input expressions dominates, leading to functions that are not smooth everywhere, such as at the points where the maximum changes hands.

Absolute Value Function Representation

Absolute value functions express the distance of a number from zero and are useful for rewriting piecewise definitions in a compact form. By utilizing properties of the absolute value, one can reformulate functions defined using the maximum operator into a single expression involving the absolute value, capturing the behavior of the function across all cases without an explicit piecewise breakdown.

Domain and Range

The domain of a function encompasses all the input values for which the function is defined, while the range includes all possible output values the function can produce. Determining the domain and range can involve analyzing the function’s definition, its piecewise components, and any transformations applied. Understanding these concepts is key to fully characterizing the behavior and limitations of any function.
