What is a linear function?

Back

A linear function is a function that graphs to a straight line, meaning it has a constant rate of change.

What is a nonlinear function?

Back

A nonlinear function is a function that does not graph to a straight line, indicating that the rate of change is not constant.

What does it mean for a function to have one output for every input?

Back

It means that for every x-value (input), there is exactly one corresponding y-value (output), which is a characteristic of functions.

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, such as translation, rotation, reflection, or dilation.

What is translation in geometry?

Back

Translation is a transformation that moves every point of a shape a certain distance in a specified direction.

What is a reflection in geometry?

Back

Reflection is a transformation that flips a shape over a line, creating a mirror image.

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but not its shape, using a scale factor.

What is the difference between a linear and nonlinear graph?

Back

A linear graph is a straight line, while a nonlinear graph is curved or has bends.

CCSS.8.F.A.3

Front

What does it mean for a graph to have more than one x-value for a y-value?

Back

It means that the function is not a function, as it violates the definition of a function where each input must have exactly one output.
