Algebra II

Part: 2

FUNCTIONS Basics!!!

You Put the Input in here

Get magic number :D

A function is an equation for which any x that can be plugged into equation will give you the equation.

Function Notation try IT: f(x)=x2+1 f(2)Function notation is a way to write functions that is easy to read and understand.

Finding Slope

Y=3x+b

There's Waldo.

Domain and RangeDomain is how far across the x value spans. And range is up in

down (y values) then you graph, it’s the span how how big or how small x can be.

Evaluating functions for specific inputs or out puts For an simple formula like this, you would just plug in your

inputs and your done. Ex: F(x)=x2+1 with F(2)

Slope intercept formY=mx+b M stands for the slope and b stands for the y

intercept. Slope ½ and corrdent (8,6) the just plug it and then just simple algebra

Graphing a linear equation.Y=2x+1, I’ll show you how to graph. Then we just graph
