Understanding Quasiconcave and Quasiconvex Functions

[@pedrocolangelo5844]

This is the first time I get the reasoning behind quasi-concavity and quasi-convexity. Thank you so much! I'm looking forward for another videos of yours!

Thank you very much! our prof started right away explaining it in 3 dimensions /using indifference curves and therefore I was a bit lost. Thanks a lot!

[@lucaflavius9295]

Very well and very clearly explained. Thank you!

THANK YOU LOVELY EXPLANATION NOW I UNDERSTAND THE LOGIC PART OF IT . SUBSCRIBED AND WILL LOOKING FOR FUTHER VIDEOS

Very good demonstration, thank you

So I do now have a bit better understanding of the definitions, but am still a bit confused regarding the following With the given definitions, the function you initially use to show quasiconvexity from 10:00 onwards, appears to also fulfil the definition for quasiconcavity, as f(x) (Which would be the Min{f(x), f(y)}) would always be lower than f(xLambda + (1-Lambda)y). Does this mean certain functions can be quasiconcave and quasiconvex at the same time? If we would now take a simple linear function f(x) = x, both the conditions for quasiconcavity and quasiconvexity would be met for any x,y combination and any Lambda [0,1], right?

[@gautamshetty2463]

Yes, quasilinear functions can be both quasiconvex and quasiconcave. Test the stronger definition for just convexity and concavity on the simple linear function you defined i.e. f(x) = x. A linear function is both convex and concave. The same intuition is behind quasilinear functions.

Are any relative textbooks recommended?

Thank you so much Sir for this marvelous video. I'm sorry Sir if you don't mind is there a way for Subtitle in English Sir not auto generated one?

[@eliali5716]

Thank you for your video, but you could have explained it in a shorter video. You just repeated again and again same sentences and same concept
