Are You Having Fun(ction)?
Am I a function?
Evaluate Functions
Domain to the Range
Linear Functions
Graph What?
100
This word is used to describe the set of all inputs for a function.
What is the domain?
100
Yes
100
f(-3) if f(x) = 2x +1
f(-3) = -5
100
Find the RANGE:
{(-2, 4), (3, 2), (2, 10)}
{2, 4, 10}
100
What is the slope of y=2x+4?
m=2
100
DAILY DOUBLE! ONLY THE TEAM THAT CHOSE THIS GETS DOUBLE POINTS!
Based on the graph of function, What is f(2)?
f(2) = 3
200
This word is used to describe the set of all outputs of a function.
What is the range?
200
DAILY DOUBLE! ONLY THE TEAM THAT CHOSE THIS GETS DOUBLE POINTS!
Is this a function and why?
No, because x's repeat at 8

DAILY DOUBLE! ONLY THE TEAM THAT CHOSE THIS GETS DOUBLE POINTS!
Let f(x) = x2 + x + 1; find f(-5).
f(-5) = 21
200
What is the domain of the function 
{-3,-1,2, 4}
200
What is the slope of y + 2x = 4
m= -2
Must get in Slope-intercept form first.
y = -2x + 4
200
Based on the graph of function. What is f(-5)?
f(-5) =0
300
A function with a graph that is a straight line.
A linear function
300
Does the following table represent a function?
x y
1 2
2 5
6 2
2 9
5 1
No, because the input (x) of 2 has two different outputs (y)
300
f(2) if f(x) = 2x - 4
f(2) = 0
300
DAILY DOUBLE! ONLY THE TEAM THAT CHOSE THIS GETS DOUBLE POINTS.
Find the RANGE in
{-6, -5, -2, 3, 5}
300
DAILY DOUBLE! ONLY THE TEAM THAT CHOSE THIS GETS DOUBLE POINTS!
What is the y intercept of y = -3x - 5?
b= -5
300
DAILY DOUBLE!!!
Based on the graph of the function, what is f(4)?
f(4) = -2
400
What visual test can prove if a function is one-to-one?
The horizontal line test
400
No, not a function.
It doesn't pass the vertical line test.
400
If g(x) = 4x2 - 1, what is g(-2)?
g(-2) = 15
400
What is the graph's domain?
{-6, -1, 2, 4, 5}
400
When graphing the function y > 4x+3, will we shade the region above or below the line?
Above, because y > mx+b
400
Based on the function, what is f(-3)?
f(-3) = -3
500
If you select this one you get all the points and no one else!
Congrats!

Function or not a function?
Not a function

If f(x)=-3x+5; if f(x)= 0 what is x?
x=5/3
500
What is the domain?
[2000,2006]

Given the function y=2x+2, what is the y-intercept.
Must be in (x,y) format!
(0,2)
500
Double it and give it to the next person! You get NO POINTS! But you have to donate DOUBLE points to the other teams. You decide how you want to split them up!
Congrats!
