Functions, Domain and Range Review

Front

Does the graph represent a function?

Back

No, because the vertical line test shows there are repeating input values.

Front

Which table does NOT represent a function?

Back

A table where at least one x-value is repeated with different y-values.

Front

What are all of the x values or inputs called?

Back

Domain.

Front

What is the range of the graph?

Back

All real numbers.

Front

Is this mapping a function or not a function?

Back

Function.

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What is the vertical line test?

Back

A method to determine if a graph represents a function by checking if a vertical line intersects the graph at more than one point.

Front

What are the y values or outputs in a function called?

Back

Range.

Front

If a function has the inputs {1, 2, 3} and outputs {4, 5, 6}, is it a function?

Back

Yes, because each input has a unique output.

Front

Can a function have the same output for different inputs?

Back

Yes, a function can have the same output for different inputs.
