The domain of this function consists of all real numbers, but the. If we input 0, or a positive value, the output is the same as the input.į\left(x\right)=x\textx $10,000. So, f(x)x f ( x ) x is the function that gives the distance between x x to 0. The subfunctions that make up the piecewise function. As you can see, piecewise functions include: A curly bracket to indicate that the function is comprised of more than one subfunction. The piecewise function above is the absolute value function. All of these definitions require the output to be greater than or equal to 0. Piecewise functions follow the following format: f (x). It is the distance from 0 on the number line. 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. For example, in the toolkit functions, we introduced the absolute value function f\left(x\right)=|x|. Generally, we can represent the absolute value function as, f(x) a x - h k, where a represents how far the graph stretches. ![]() This function is also known as the modulus function and the most commonly used form of the absolute value function is f(x) x, where x is a real number. ![]() The values that are y-coordinates of points on the graph are all real. An absolute value function is a function in algebra where the variable is inside the absolute value bars. Sometimes, we come across a function that requires more than one formula in order to obtain the given output. Answer: The function is defined for all values of x, so the domain is all real numbers.
