Warm-ups! Each day we will complete a warm-up. This is the basic warm-up structure: Use a format like this on your own paper.

M 3 U 1 D 1 Introduction to Math 3 Objective: To review functions and function notation.

Main topics in Math 3 H Unit 1: Functions and their Inverses

Is it a Function? Determine if the relationships stated below represent a function. • (x, y) = (boys name, color of hair) • (x, y) = (color of hair, boys name) • (x, y) = (price of calculator, amount of sales tax) • (x, y) = (zip code of student, student height) • (x, y) = (miles driven since you last filled up, amount of gas in gas tank)

? With your group, create 3 additional relationships. Follow the criteria below when creating the relationship. Not A Function Is still a function if you exchange the x and y variables.

Just to summarize What is a function? In modern mathematics, a function is defined by its set of inputs, called the domain; a set containing the set of outputs, and possibly additional elements, as members, called its codomain (or target); and the set of all inputoutput pairs, called its graph.

Just to summarize What makes a function? A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. . Relation from X to Y that is a function: { (1, d) , (2, d) , (3, a) } This is a function since each element from X is related to only one element in Y.
