Functions

A function is relation that assigns exactly one value in the Range to each value in the Domain.

This does not mean you cannot have multiple values in the Domain assigned to one value in the Range.

The values in the domain are called elements, while the values in the range are called correspondents.



The Domain (or elements of the domain) can also be called:

• X
• Input
• Independent Variable

The Range (or correspondents of the range) can also be called:

• Y
• Output
• Dependent Variable

Y= f(x)

Note: Anytime you see "y-squared" it is not a function because it will have 2 x values for every y value. Also, a circle cannot be a function because it includes "y-squared".

Graphing functions can result in many different types of graphs such as:

Linear Function:

Hyperbola:
Parabola:

Trinomial:

and many others!

So... that's functions... I don't know what else to say so... yeah... I'm gonna stop typing now... and you're just gonna have to deal with it... yeah... well... YOU LOST THE GAME!

Section 2.1

Hello fellow class members, first i am produce to announce that book licker has been accepted into urbandictionary.com, http://www.urbandictionary.com/define.php?term=book%20licker will be up very shorty.

This section in the book has to do with equations. Woohooooo!!!!! And overall this section is what we learned in 8th grade (or 7th for the chosen ones) but it just takes it into the next level of difficulty.

Equation- a statement where two quantities or expressions are equal. like the one my dad has tattooed on his back.

or one as simple as y=mx+b, but thats not as fun......

Algebraic equation- contain algebraic expressions such as polynomails, rational expressions, radicals and so on.

Conditional equation- same as above but if there are numbers in the domains of the expressions that are not solutions like 16=x^2

Identity- An equation where every number in the domains of the expressions in an algebraic equation is a solution..... 2x+64=2(x+32)

Solving an equation

(2x+5)(5x-3)=4x+10 simplify 4x+10

(2x+5)(5x-3)=2(2x+5) take away 2x+5 on both sides

5x-3=2 add three on both sides

5x=5 divide

x=1

An equation containing rational expressions

the website above sums it all up completely
