Key Concepts

Order of Operations

The order of operations refers to the rules governing the sequence in which arithmetic operations should be performed (commonly remembered as PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). This concept is crucial to correctly evaluate the function after substituting the input value.

Linear Functions

A linear function is one that can be written in the form f(x) = mx + b, where m and b are constants, and its graph is a straight line. Linear functions involve operations such as multiplication by a constant and addition of a constant, making them straightforward to evaluate using substitution and the order of operations.

Function Notation

Function notation is a way of representing functions with symbols like f(x) or g(x), where the expression associated with the function is written in terms of the variable x. This notation indicates that to find the output of the function, you substitute the input value into the formula in place of x.

Substitution

Substitution is the process of replacing the variable in the function's expression with a specific value. This step is essential when evaluating a function at given points, as you directly insert the input value into the formula to compute the corresponding output.
