Front

What is function notation?

Back

Function notation is a way to represent functions in mathematics, typically using symbols like f(x), g(x), etc., where 'f' or 'g' denotes the function and 'x' is the input variable.

If f(n) = 4 - 10n, what is f(n) when f(n) = 14?

Back

Set 4 - 10n = 14. Solving gives n = -1.
