🎯✏️Functions Practice Test (Option 2)

Front

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

How do you determine the domain from a graph?

Back

To determine the domain from a graph, identify the x-values that the graph covers. The domain is the range of x-values for which the graph exists.

Front

What is a function?

Back

A function is a relation that assigns exactly one output value for each input 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 if a mapping is not a function?

Back

If a mapping is not a function, it means that at least one input value is associated with multiple output values.

Front

How do you identify the domain from a set of ordered pairs?

Back

To identify the domain from a set of ordered pairs, list all the first elements (x-values) of the pairs.

Front

What is a function rule?

Back

A function rule is an equation that describes the relationship between the input and output of a function.

Front

How can you find a function rule from a table of values?

Back

To find a function rule from a table of values, look for a consistent pattern in the input-output pairs and derive an equation that fits.

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

What is the difference between a relation and a function?

Back

A relation is any set of ordered pairs, while a function is a specific type of relation where each input is associated with exactly one output.
