Flashcard review 5.1-5.2 Functions and Linearity

Front

Is this graph a function or not a function? Use VLT.

Back

Not a Function

Front

All of the y values or outputs are called what?

Back

Range

Front

Is this mapping a function or not a function? Look at the domain/independent.

Back

Not a Function

Front

Is this table a function or not a function? Look at the domain/independent.

Back

Not a Function

Front

Is the function represented by the table linear or nonlinear?

Back

Nonlinear

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

What is the Vertical Line Test (VLT)?

Back

A method to determine if a graph represents a function; if a vertical line intersects the graph more than once, it is not a function.

Front

What are the domain and range of a function?

Back

Domain: all possible input values; Range: all possible output values.

Front

What is a linear function?

Back

A function that graphs to a straight line, represented by the equation y = mx + b.

Front

What is a nonlinear function?

Back

A function that does not graph to a straight line, may include curves or other shapes.
