This was a GREAT and thorough set of explanations for this FRQ! This seems like one of the most challenging ones asked this year and you gave great tips throughout. Some things that stood out - a very helpful reminder right away that we are looking at the graph of f ' and not f...this is a trap I've seen students fall into that throws off the rest of the problem, so great reminder about reading the info provided carefully! I thought your breakdown of part c) was phenomenal - the separate limit calculations for the numerator and denominator to notice the indeterminate form was very organized, the justification of why f(2) was the same value as the limit was well-explained, and the reminder about needing limit notation when finally utilizing L'Hospital's rule was very helpful. I also thought your breakdown of the Candidates Test in part d) was very clear to follow and made it easy to see what work College Board expects to see written down. Another excellent and organized set of explanations from your fantastic math channel - the quality and helpfulness of these videos is ...an ABSOLUTE MAX! 😁 Thanks for posting - looking forward to future videos!
