Function notation  Relations and Functions
Function notation
Function notation is another way to express the y value of a function. Therefore, when graphing, we can always label the yaxis as f(x) too. It might look confusing, but let us show you how to deal with it.
Basic Concepts
 Solving linear equations using multiplication and division
 Solving twostep linear equations: $ax + b = c$, ${x \over a} + b = c$
 Solving linear equations using distributive property: $a(x + b) = c$
 Solving linear equations with variables on both sides
