Front

What is a function in mathematical terms?

Back

A function is a relation that assigns exactly one output for each input.

Front

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.

Front

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.

Front

What happens to a shape when the scale factor is greater than 1?

Back

The shape undergoes an enlargement.

Front

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.

Front

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.

Front

How do you identify corresponding sides in similar figures?

Back

Corresponding sides in similar figures are the sides that are in the same relative position in each figure.

Front

What is the significance of the letter 'G' in proportions?

Back

The letter 'G' typically represents a specific ratio or relationship that must hold true in a proportion.

Front

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).
