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
