Front

What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

Define the domain of a function.

Back

The domain of a function is the complete set of possible values of the independent variable (x) for which the function is defined.

Front

Define the range of a function.

Back

The range of a function is the complete set of possible values of the dependent variable (y) that the function can output.

Front

What does it mean for a function to be constant over an interval?

Back

A function is constant over an interval if it produces the same output value for every input value within that interval.

Front

How do you determine where a function is increasing?

Back

A function is increasing on an interval if, as the input values increase, the output values also increase.

Front

How do you determine where a function is decreasing?

Back

A function is decreasing on an interval if, as the input values increase, the output values decrease.

Front

What is a maximum value of a function?

Back

The maximum value of a function is the highest point on the graph of the function.

Front

What is a minimum value of a function?

Back

The minimum value of a function is the lowest point on the graph of the function.

Front

What does the notation [-3, 4] represent?

Back

The notation [-3, 4] represents a closed interval that includes all numbers from -3 to 4, including -3 and 4.

Front

What does the notation (-∞, -1) represent?

Back

The notation (-∞, -1) represents an open interval that includes all numbers less than -1, but not -1 itself.
