For this inequality question why is one equal to and the other not?? I tried got both equal to how do u figure this

look on the graph bro two branches one where theres an asymptote and one intersection where x=1. If theres an asymptote, theres no chance of it =ing to -1. Also just observe the denom x+1, so x=/-1

im sorry dont get it

Note theres an asymptote at x=-1. Hence, the inequality cannot include x=-1

fast way to notice this is by observing the denominator. If x was -1 in that inequality you provided, you would get 2/0= infinite, which would obviously not satisfy the inequality. Therefore we do not include the x=-1 case.

look at this example none of that is needed...

I just started year 11 and ur throwing all these terms on me .

Nevermnd dont waste time on me

If someone could explain the question above in simple terms It would be appreciative

Isn't this comment also applicable to your main question?

denominator can never be 0 as, well, how do you divide by infinity? you can't. so it's an asymptote.

and?

???

 

[eternallyboreduser]

just multiply both sides by the denominator squared, note that denominator cannot equal 0

Just to clarify, you're asking why and not ?

yeah hes tryna ask why its x<-1 instead of x<=-1

 

[Tryingtodowell]

Just to clarify, you're asking why and not ?

yeah and why the other has the equal to sign

 

[eternallyboreduser]

yeah and why the other has the equal to sign

its cos x=-1 is an asymptote, thus not part of the solution
