Function notation is the standard language mathematicians use to describe and evaluate functions. Instead of writing “y equals 2x plus 3,” we write \(\color{blue}{f(x) = 2x + 3}\), which makes it clear we are talking about a function named f that depends on the variable x. Once you understand function notation, evaluating functions becomes a […]
