Key Concepts

Domain

The domain of a function is the set of all possible values of the independent variable (typically x) for which the function is defined. In the context of linear functions, the domain is often all real numbers, meaning that the function can accept any real input value.

Set-builder Notation

Set-builder notation is a mathematical shorthand used to describe a set by specifying the properties that its members must satisfy. For instance, a solution to an inequality can be expressed in set-builder notation by indicating the variable along with the condition it must meet, which provides a clear and concise description of all elements in the set.

Linear Function

A linear function is a mathematical function that can be written in the form f(x) = mx + b, where m and b are constants, and its graph is a straight line. This function exhibits a constant rate of change, meaning that as the input (x) increases, the output (y) changes by a fixed amount determined by the slope (m).

Inequalities

Inequalities are expressions that show the relationship of one quantity being less than, greater than, or equal to another. When dealing with linear functions, solving inequalities such as f(x) < 0 or f(x) ? 0 involves determining the intervals of x where the function’s output meets the given condition. This is typically done by finding the point of equality and then testing intervals around that point.
