What is the domain of a function?

Back

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

Front

How can you determine if a relation is a function?

Back

A relation is a function if each input (x-value) has exactly one output (y-value).

Front

What does the notation f(x) represent?

Back

f(x) represents the output of the function f for a given input x.

Front

What does the equation g(x) = f(x) - 4 do to the graph of f(x)?

Back

It shifts the graph of f(x) down by 4 units.

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 relation?

Back

A non-function relation is one where at least one input (x-value) is associated with multiple outputs (y-values).

Front

What is the difference between domain and range?

Back

Domain refers to the input values of a function, while range refers to the output values.

Front

What is a 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 function to be linear?

Back

A linear function is a function that graphs to a straight line, typically in the form f(x) = mx + b.
