What is the definition of function?

• Has inputs and outputs
• Every input has only ONE output
• Inputs have different outputs every time
• x-values and y-values

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values
• No, because the vertical line test shows there are repeating input values

Is this a function? 

• Yes 
• No

What is the domain?

• the set of all x-values

• the set of all y-values

What is the range?

• the set of all x-values

• the set of all y-values

Discrete or continuous data?

• Discrete

• Continuous

Which of these is NOT the same

• Range
• Input
• Dependent Value
• Y-Value

The vertical line test

• determines of a relation is a one-to-one function.

• determines if a relation is a function.

• determines if a function is a relation.

• determines if a one-to-one function is a function.
