This tutorial is for Ms. Cranga's Algebra 1 class 9/29. This is the introduction to functions. Tomorrow in class we will be working with these concepts.

Tutorial

Today we will be introducing the functions. We will learn what a function is and how to evaluate a function at given input values. Then, we will learn how to determine if a point is a solution to a given function without graphing the function. We will be using these skills in class tomorrow.

This is the order in which you should be conducting calculations. Parthesis first, exponents, multiplcation, division, addition, and lastly subtraction. This will help us when we are evaluating functions at given input values.

PEMDAS

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

This Prezi will tach you function basics, and how to evaluate functions at given input values. Tomorrow in class we will be using the material from this Prezi. Please take notes

This video will serve as a demonstration to determine if a point is a solution to a given function. Having a strong knowledge of order of operations will help you with these types of problems. Please take notes.

**Function**: A relationship between a set of input values and a set of output values

**Input Value:** A value that we put in to a function, x values

**Output Value**: A value that we generate from a function, y values
