In Algebra, a function is a relation between a set of inputs (independent variables) and a set of possible outputs (dependent variables). Each input is related to exactly one output. Functions are often written as f(x), where x is the input variable, and f(x) is the output.
A function table, also known as a value table, is a tool used to organize and display the values of a function for different inputs. It helps students visualize how the function behaves and understand the relationship between the input and output variables.
