Functions 2Lecture contents Domain and RangeNotations for domain and rangeDomain restrictionDomain of Purposely Restricted FunctionsDomain of rational functionsDomain of radical functionsDomain of both Rational and Radical FunctionsLecturer: A. S. Brwa – Faculty of Engineering – Calculus I – Lecture 5 –Domain and Range Tishk International University
Domain & Range 3Definitions of Domain & Range: Domain:is the set of all x values to which a function assigns a corresponding a real y value. Or the domain is the set of x-values where the function is defined (All input values of x).Range:is the set of all y values that result from x values. (All output values of y).Lecturer: A. S. Brwa – Faculty of Engineering – Calculus I – Lecture 5 –Domain and Range Tishk International University

Domain & Range 5Notations for Domain and RangeThere are three main notations to represent the domain or range. 1.Roster Notation:2.Set-Builder Notations:3.Interval Notation:Lecturer: A. S. Brwa – Faculty of Engineering – Calculus I – Lecture 5 –Domain and Range Tishk International University
Domain & Range 6Notations for Domain and Range1.Roster Notation:For Example:Determine the domain and range of the following set of ordered pairs. Lecturer: A. S. Brwa – Faculty of Engineering – Calculus I – Lecture 5 –Domain and Range Tishk International University
Domain & Range 7Notations for Domain and Range2.Set-Builder Notations: For Example: Lecturer: A. S. Brwa – Faculty of Engineering – Calculus I – Lecture 5 –Domain and Range Tishk International University
Domain & Range 8Notations for Domain and Range3.Interval Notation:Open brackets ( )Closed brackets [ ]One side open the other side is closed ( ] or [ ) (x, y)(2, 8)[2, 8] (2, 8] = 3, 4, 5, 6, 7 = 2, 3, 4, 5, 6, 7, 8 or [2, 8)= 3, 4, 5, 6, 7, 8 = 2, 3, 4, 5, 6, 7 Lecturer: A. S. Brwa – Faculty of Engineering – Calculus I – Lecture 5 –Domain and Range Tishk International University
