Am I a function?
Evaluate Functions
Domain to the Range
Linear Functions
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
200
This word is used to describe the set of all outputs of a function.
What is the range?
200
Is this a function and why?
No, because x's repeat at 8
200
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
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
Find the RANGE in
{-6, -5, -2, 3, 5}
300
What is the y intercept of y = -3x - 5?
b= -5
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
