The domain of a function f consists of all values of x for which the value f(x)is defined. For a function defined by a table, its domain consists of numbers in the first
If only the rule y = f(x) is given, then the domain is taken to be the set of all real x for which the function is defined. For example, y = √ x has domain; all real x ≥ 0. This is sometimes referred to as the natural domain of the function. 1.1.4 Range of a function For a function f: X → Y the range of f is the set of y-values such that ...
Finding Domain for Functions -This tutorial will focus on finding the Domain algebraically for Polynomial, Rational, and Radical Functions. (Knowledge of Interval Notation is assumed.) What is Domain and why does it matter? -The Domain for a function is its input, just as its output is called Range.
To find the domain of a function, consider any restrictions on the input values that would make the function undefined, including dividing by zero, taking the square root of a negative number, or taking the logarithm of a negative number.

Name:_____ Functions: Domain/Range . Give the domain and range for each function. 1. 𝑓𝑓(𝑥𝑥) = √𝑥𝑥+ 4
recognise when a rule describes a valid function, be able to plot the graph of a part of a function, find a suitable domain for a function, and find the corresponding range. 1. What is a function? Here is a definition of a function. A function is a rule which maps a number to another unique number.
