THANKSGIVING DAY BACK REVIEW

What is a function in mathematics?

Back

A function is a relation that assigns exactly one output (y) for each input (x).

Front

How can you determine if a set of ordered pairs represents y as a function of x?

Back

A set of ordered pairs represents y as a function of x if no two pairs have the same x-value.

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function. If a vertical line intersects the graph at more than one point, it is not a function.

Front

What does it mean for a mapping diagram to represent a function?

Back

A mapping diagram represents a function if each input value (x) is connected to exactly one output value (y).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represents a point in a coordinate system.

Front

What is the definition of a domain in a function?

Back

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

Front

What is the definition of a range in a function?

Back

The range of a function is the set of all possible output values (y-values) that result from the function.

Front

What is an example of a function?

Back

An example of a function is f(x) = 2x + 3, where each x-value has a unique y-value.

Front

What is a non-function?

Back

A relation is a non-function if at least one input value (x) is associated with more than one output value (y).

Front

How can you identify a function from a table of values?

Back

A table of values represents a function if each x-value corresponds to only one y-value.
