It's so much fun to go through these questions with you, like all the memories starting to come back. Definitely great work!

That's very kind of you ☺️

[@earthchicken2233]

for 6b 8:07 can't you just say f''(2) = 0 therefore must be point of inflection rather than f''(2) < 0 for x < 2 and
f''(2) > 0 for x > 2? why do you have to show that it changes sign? doesn't f''(2) = 0 already assume that?

[@MathsWithMrLim]

Good question but that's just it... f''(2)=0 does NOT guarantee a point of inflection. Watch the other video I linked on points of inflection (or check your textbook) ruclips.net/video/LmHcF-xzipg/видео.html
Good luck in your exams EarthChicken ☺️
