In simple terms, a function is a relation between a set of inputs and a set of possible outputs. It takes an input value, performs a series of operations on it, and produces an output value. Evaluating a function involves determining the output value for a given input. For example, consider a simple function: f(x) = 2x + 3. To evaluate this function for an input value of 2, you would replace x with 2 and perform the operations: f(2) = 2(2) + 3 = 7. This process is called substitution.

Graphing a function involves plotting points on a coordinate plane using the function's x- and y-values.
