Understanding Function Notation and Graphing

To avoid using variables

To solve equations faster

To represent a function in terms of its input

To simplify multiplication

F(x) is a function, while f * x is multiplication

F(x) is always greater than f * x

F(x) and f * x are the same

F(x) is used only in calculus
