2
Linear Functions
This year we talked about Linear Functions and other functions that came from them.
3
Linear Absolute Value Functions
Linear absolute value functions are one of the functions we learned about from linear functions.
4
Exponential Functions
Aside from lines, we talked about a curvy function known as the exponential function.
5
Quadratic Functions
The next place to go is our other curvy friends: Quadratic Functions....

7
Key Structures:
y-intercept: where the graph crosses the y-axis
x-intercept: where the graph crosses the x-axis
8
Multiple Choice
Where is the y-intercept in this graph?
9
Multiple Choice
Where is the x-intercept in this graph?
10
Key Features: Absolute Value
Vertex (corner point): where the graph turns from decreasing to increasing
Axis of Symmetry: an invisible line that cuts the graph into two equal halves through the vertex
11
Multiple Choice
Where is the vertex of this graph?
12
Multiple Choice
Where is the axis of symmetry of this graph?
13
Open Ended
Compare the linear function to the Quadratic - what do you notice about the x-intercepts?
14
Open Ended
Compare the Linear Absolute Value Function to the Quadratic Function. What key feature(s) do they share?
15
Quadratics are the same!
Quadratics have all of these key structures too!
16
3 forms of Functions
Linear functions have 3 different forms, each that give different advantages.
17
Multiple Choice
Which form of line is this?
18
Multiple Choice
Which form of line is this?
19
Multiple Choice
Which form of line is this?
20
Quadratics are the same!
Quadratics also have 3 forms of functions that have different uses!
21
22
X-intercepts AKA "Zeros"
Quadratics have a special structure called "Zeros". They are called this because they are where the quadratic equals 0!
