Practice with Relations and Functions

What do you call a relation where every input has exactly one output?

• Single Relation
• Mapping
• Representation
• Function

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

What is the range of the following graph?

• R: {-5, -1, 0 , 1, 5}

• R: {-4, -2, 0, 3, 6}

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
