### LG 1: Introduction to Functions

 UNIT 8 - Relations/Functions/Graphs                                         Learning Objective:   BTEOTPSWBAT......determine if a relation is a function by looking at a table, a mapping diagram, or a graphevaluate a function for a given value using an equation or graphState the domain and range of a function using interval notation, determined from a graphWARM UP - The BasicsWARM UP PRACTICE: Convert between tables/graphs/mapping - IXL1. IS IT A FUNCTION? (from a table)Since the x value repeats in the first example, it is NOT A FUNCTION! We only care about the x value. 2. IS IT A FUNCTION? (from a mapping diagram)In the 2nd example, we would have the ordered pairs (5,2) and (5,9).  You can see that the domain value(x value) repeats so it is NOT A FUNCTION.Identify Functions (Table & Mapping)- IXL3. IS IT A FUNCTION? (from a graph)Use the vertical line test:Video : Vertical Line Test - Virtual NerdVertical Line Test - IXL4.
