Solving 1-Variable Inequations Graphically

Solving inequations that involve one variable can be done either purely algebraically or graphically. The algebraic procedure can be somewhat cumbersome, whereas the graphical method is more intuitive. The next three lessons show the graphical method that can be used to solve 1-variable inequations involving an absolute value, a square root, or a rational expression.

Learning Goals:

  • Find the solution set for a 2-variable absolute-valued inequation
  • Find the solution set for a 1-variable radical inequation
  • Find the solution set for a 1-variable rational inequation
