AM Algebra 1 Fall Final Review

Front

What is a function?

Back

A function is a relationship between two sets of values where each input (x) has exactly one output (y).

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y) that the function can produce.

Front

What does it mean for a set of ordered pairs to represent y as a function of x?

Back

It means that for every x-value, there is only one corresponding y-value.

Front

Identify the independent variable in a study about test scores and study time.

Back

The independent variable is the time spent studying.

Front

Identify the dependent variable in a study about test scores and study time.

Back

The dependent variable is the grade on the test.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represent a point on a graph.

Front

What does it mean if a function is not a function?

Back

It means that at least one x-value is paired with more than one y-value.

Front

How do you determine the domain from a graph?

Back

The domain can be determined by identifying all the x-values that the graph covers.

Front

How do you determine the range from a graph?

Back

The range can be determined by identifying all the y-values that the graph covers.
