Key Concepts

Domain of a Function

The domain of a function is the complete set of input values for which the function is defined. Determining the domain involves identifying any restrictions on the variable, such as division by zero or negative values under even roots, ensuring that only valid inputs are included.

Rational Functions

Rational functions are expressed as the ratio of two polynomials. The key restriction for these functions is that the denominator cannot be zero, as division by zero is undefined. Finding the domain of a rational function typically involves solving for the values that make the denominator zero and excluding them from the domain.

Interval Notation

Interval notation is a concise way to express subsets of the real numbers. It uses parentheses and brackets to indicate whether endpoints are excluded or included, respectively, making it a useful tool for clearly presenting the domain of a function once the restricted values have been identified.

Operations on Functions and Combined Domains

When performing operations such as addition, subtraction, multiplication, or division on functions, the resulting function is only defined where both original functions are defined, subject to any additional restrictions created by the operation. This means the domain of the resulting function is the intersection of the original domains, taking into account any further exclusions such as division by zero during the operation.
