Why are there no examples, quizzes, or videos under functions on how to work a difference quotient equation? This is a missing piece of critical training that I need.
i too could really use this content. it is a key piece of what we are learning and i really like learning from the videos here- it often helps me when the teacher doesnt not explain things in a way i can understand.
