Unit 2 REVIEW

Front

What is a function in mathematics?

Back

A function is a relation in which each input (x-value) is associated with exactly one output (y-value).

Front

How can you determine if a relation is a function?

Back

A relation is a function if no x-value is paired with more than one y-value.

Front

What is a proportional relationship?

Back

A proportional relationship is one in which two quantities maintain a constant ratio or rate.

Front

How can you identify a proportional relationship in a table?

Back

A proportional relationship can be identified in a table if the ratios of corresponding values are constant.

Front

What is a mapping in mathematics?

Back

A mapping is a representation of how each element in one set (domain) is paired with an element in another set (range).

Front

What does it mean for a table to be non-proportional?

Back

A non-proportional table does not maintain a constant ratio between the x-values and y-values.

Front

What is the significance of the x-value in a function?

Back

The x-value represents the input of the function, which determines the corresponding y-value (output).

Front

What is the significance of the y-value in a function?

Back

The y-value represents the output of the function, which is determined by the corresponding x-value (input).

Front

What is the definition of a constant ratio?

Back

A constant ratio is a fixed relationship between two quantities, where the ratio remains the same regardless of the values.

Front

How do you describe the motion of an object in a segment like O-A?

Back

The motion can be described in terms of direction (e.g., moving forward, backward) and speed.
