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

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 do you find the domain of a function from a graph?

Back

To find the domain from a graph, identify all the x-values for which the graph has points.

Front

How do you find the range of a function from a graph?

Back

To find the range from a graph, identify all the y-values that the graph reaches.

Front

What is a polynomial expression?

Back

A polynomial expression is a mathematical expression that consists of variables raised to whole number powers and coefficients.

Front

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the expression.
