How can you determine if a mapping is a function?

Back

A mapping is a function if every input has exactly one output; if any input has multiple outputs, it is not a function.

What is a scale factor in dilation?

Back

The scale factor is a number that scales, or multiplies, the dimensions of a shape during dilation.

What does it mean for a graph to be proportional?

Back

A graph is proportional if it passes through the origin and has a constant ratio between the variables.

What is a non-proportional relationship?

Back

A non-proportional relationship does not maintain a constant ratio between the variables and does not pass through the origin.

What is the definition of dilation in geometry?

Back

Dilation is a transformation that alters the size of a figure but maintains its shape.

Front

What is the difference between enlargement and reduction in dilation?

Back

Enlargement increases the size of a figure (scale factor > 1), while reduction decreases the size (scale factor < 1).
