WordPress Shortcode. Published in: TechnologyBusiness.You are now deeper in your Algebra journey and you've just been introduced to this term called a "function". What in the world is a function? Although it may seem at first like a function is some foreign creature in Algebra land, a function is really just an equation with a fancy name and fancy notation.
If you are nervous, Algebra Class offers many lessons on understanding functions. Click here to view all function lessons.
A function is a relationship between two variables. The first variable determines the value of the second variable. The value of the first variable corresponds to one and only one value for the second variable. Yes, I know that these formal definitions only make it more confusing.
Let's take a look at this another way. I always go back to my elementary years when we learned about functions - but never called them functions. We had what was known as an "in and out box".
Some teachers now call it a "Function Box" and this is why:. Here's a picture of an algebra function box. Imagine the equation being the center of the function box. You put a number in, the function box performs the calculation and out pops the answer. Let's take a look at an example with an actual equation.
Notice how our equation has 2 variables x and y. When we input 3, the function box then substitutes 3 for x and calculates the answer to be 7. No other number will correspond with 3, when using this equation. If you input another number such as 5, you will get a different output. No other number can correspond with 5, when substituting into this equation. Therefore, this equation can be labeled a function. It seems pretty easy, right? It seems like all equations would be considered functions.
Take a look at an example that is not considered a function. When we input 4 for x, we must take the square root of both sides in order to solve for y. Therefore, this does not satisfy the definition for a function: "the value of the first variable corresponds to one and only one value for the second value". We have more than one value for y. Hopefully with these two examples, you now understand the difference between an equation that represents a function and an equation that does not represent a function.
You will find more examples as you study the lessons in this chapter. So, what kinds of functions will you study? In Algebra 1, we will study linear functions much like linear equations and quadratic functions. As you progress into Algebra 2, you will be studying exponential functions.

Title: Algebra 2 1 Algebra 2 Section Linear Equations 2 What You'll LearnWhy It's Important To identify equations that are linear and graph them, To write linear equations in standard form, and To determine the intercepts of a line and use them to graph an equation.
You can write equations to represent relations in education, physics, and geology 3 Connection Physics You might guess that sound would travel fastest through air since air is less dense than other mediums like water, glass or steel. However, just the opposite is true. Sound travels though air most slowly of all. Through air it travels feet per second, through water about feet per second, and through glass and steel about 16, feet per second.
Since the value of y depends on the value of x, y is called the dependent variable, and x is called the independent variable.
In this graph the points appear to lie on a line. This graph is a function. The line would contain an infinite number of points, whose ordered pairs are solution of the equation y x. An equation whose graph is a line is called a linear equation. A linear equation is an equation that can be written in standard form Ax By C 7 Standard Form of a Linear Equation The standard form of a linear equation is Ax By C,where A, B, and C are real numbers and A and B are not both zero Usually A, B, and C are given as integers whose greatest common factor is 1 When variables other than x are used, assume that the letter coming first in the alphabet represents the domain or horizontal coordinate.
Identify A, B, and C. A function is linear if it can be defined by f x mx b, where m and b are real numbers.
In the definition of a linear function, m or b may be zero. The graph is a horizontal line. This function is called a constant function. If f x 0, the function is call the zero function.
