# Why does LRAC not connect the minima of SRAC curves? [duplicate]

Can anyone please provide an intuitive explanation and proper mathematical reason for non-intersection of SRAC and LRAC at the minimas of SRAC?

I am seeing conflicting [1] [2] answers on the site regarding this. My textbook (Chapter 10, page 355) too does not do a great job in explaining the graph:

• @AdamBailey it looks like duplicate to me too but I am not sure to close it with mod vote outright consider voting close – 1muflon1 May 6 at 11:52
• @AdamBailey More like literal duplicate. I am going to shamelessly advertise my simple explanatory example before voting to close though. – Giskard May 6 at 11:56
• @Giskard What is y in your explanation? (I don't have sufficient reputation to comment) – reasonStore May 6 at 12:55
• @AdamBailey The answer linked is not intuitive or exhaustive, it just has a complicated use case of Cobb Douglas; and neither does it cover why at minima of LRAC, SRAC also has its minima. – reasonStore May 6 at 12:57
• @reasonStore Output/quantity. Your textbook seems to denote it by $q$. Also Adam Bailey is linking to a different question then I am; I am linking to the one with the Cobb-Douglas answer. You can read his - perhaps - easier to comprehend answer behind his link. – Giskard May 6 at 14:20
