A2U1 Domain and Range

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

The domain can be determined by identifying the x-values that the graph covers. It includes all x-values for which there are corresponding y-values.

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 determine the range from a graph?

Back

The range can be determined by identifying the y-values that the graph covers. It includes all y-values that correspond to the x-values in the domain.

Front

What does it mean to factor an expression?

Back

Factoring an expression means rewriting it as a product of its factors, which can simplify solving equations or analyzing functions.

Front

What is the Greatest Common Factor (GCF)?

Back

The GCF is the largest factor that divides two or more numbers or expressions without leaving a remainder.

Front

How do you factor by using GCF?

Back

To factor by GCF, identify the largest common factor of the terms in the expression and factor it out.

Front

What is a polynomial?

Back

A polynomial is a mathematical expression that consists of variables raised to non-negative integer powers and coefficients.

Front

What is the standard form of a polynomial?

Back

The standard form of a polynomial is written in descending order of the degree of its terms, from highest to lowest.

Front

What is the difference between domain and range?

Back

Domain refers to the set of input values (x-values), while range refers to the set of output values (y-values) of a function.
