Determining Functions

Front

Determine if the equation is linear: y = x^2 + 3

Back

Nonlinear

Front

Determine if this is a function: {(1, 2), (1, 3), (2, 4)}

Back

Not a Function

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What is a linear function?

Back

A function that graphs to a straight line.

Front

What is the vertical line test?

Back

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

Front

What is a nonlinear function?

Back

A function that does not graph to a straight line.
