Linear Functions
A function `f` defined by an equation of the form `y=mx+b`, where `m` and `b` are real numbers, is a LINEAR function and can be written `f(x)=mx+b`.
If that is too confusing, forget the `f(x)` and just substitute `y` instead. Solve for the `f(x)` given the values specified in the domain (the `x` values) .

Inequalities and Absolute Value
If the inequality with absolute values looks like: `| A | < b`, then we solve the conjunction `-b < A < b`. Think of a number line, and the solution will be within the bounds of `-b` and `b`. This also works with `≤`.
If the inequality with absolute values look like: `| A | > b`, then we solve the disjunction `A < -b` OR `A > b`. On the number line, these solutions look like arrows on the outside of the values `-b` and `b`. This works for `≥` as well.
