1. WELCOME TO MY ALGEBRA/CHEMISTRY PRESENTATION

2. Introduction - Algebra Content: * Sequences * Functions - Chemistry Content: * Atomic Structure * Periodic Table Trends

3. Sequences: What are They?  A Sequence is a trend/pattern.  There are two types of sequences: Arithmetic & Geometric.  Arithmetic Example: 4, 7, 10, 13  Geometric Example: 2, 4, 8, 16

4. Sequences: How to Identify them  Sequence A: -4, -1, 2, 5  Sequence G: 48, 24, 12,6 nt(n) 0 1 2 3

5. Sequences: How To Graph Them

6. Sequences: Writing Equations  Arithmetic: * t(n)= (common difference)n + the “0”term. *Example: 8, 11, 14, 17 * t(n)=__________n+ ___________  Geometric: *t(n)= ( initial term)(multiplier)n * Example: 2, 4, 8, 16 * t(n)= (_______)( ________)n

7. Sequences: Word Problems  Every minute a computer sends a virus to 5 new computers. The following minute the original computer sends its virus to 5 new computers, and each computer that received it the first time sends it to 5 more. # of minutes# of infected computers 01 16 2 3 4

8. Functions: What are they?  A function is an equation where there’s an input and an output.  Function Notation: f(x)= f “of”x  Domain & Range
