Shouldn’t the intervals with real numbers have brackets around them?

[@the_realyogstroyer4200]

Arent you gonna put open or closed intervals since you know where it ends

[@isabellagarcia6761]

Thank you so much TwT

[@abdullahmufti]

Can anyone please explain to me why the parantheses is not closed? For example, cant we write it as [3,6] instead of (3,6)

[@jade.clarisse_]

I was questioning the exact same thing 😟

[@KariaJaimes]

no unions are needed??

[@mariaohara4154]

i wish u were my teacher😪

[@BiscuitBalls]

i need u as my teacher

[@favageseline2081]

But why is it a parenthesis and not a square bracket?

[@brianmclogan]

At a given point when the graph changes from increasing to decreasing or vice versus the actual point cannot be included in both so parenthesis to exclude
