3.2 Flashcards on Identifying Functions

Front

Back

Yes, because each input goes to one and only one output

Front

Is the relation a function?

Back

Front

What is the vertical line test?

Back

A method to determine if a graph represents a function by checking if any vertical line crosses the graph more than once.

Front

Can a function have two identical outputs for different inputs?

Back

Yes, a function can have the same output for different inputs, but not the same input for different outputs.

Front

Can a vertical line intersect a function more than once?

Back

No, if a vertical line intersects a graph more than once, it is not a function.

Front

What defines a function in terms of inputs and outputs?

Back

A function is defined such that each input has exactly one output.
