Am I a function?
What is No?
Is this a function and why?
What is no, because x's repeat at 8?
Is the shaded region
* increasing or decreasing
*Constant or not constant?
What is a constant decrease?
g(x) = 5x - 10 , find g(2)
Linear or Expoential?
Exponential
This word is used to describe the set of all y-values for a function.
output/range
What is YES! NO input values repeat.
Find the slope of the line below using rise/run.
2/3
Rise = 2
Run = 3
f(x) = x + 1 Find f(4)

A population of bees is growing. Every week there seem to be 20 more bees.
Is this situation linear or exponential?
Linear (adding 20 each week)
This word is used to describe the set of all x-values for a function.
inputs/domain
This graph is not a function.
What is Graph 1?
What is happening on the graph between x=2 and x=3?
What is decreasing?
Solve:
f(2) f(-4)
f(2) = 2
f(-4) = -1
Is the following equation linear or exponential?
y = 5x + 2
Linear?
This word describes a relation that pairs each x value with only one y value.
function
Is the following relation a function?
What is yes?

What is y=13?
g(x) = 2 - x
solve for x when g(x) = 2.5
