sqrt{x^2-9}

As the value of x approaches 14, is there a limit to the function? If so, what is it?

C

How do you not see that?

Bump.

Holy shit dude, really? This is actually one of the saddest homework threads I've seen. You could at least post a problem someone would have reason to struggle with.

I was thinking it might be sqrt(187) but idk wtf the rules are.

ty for help nigs

New one. I'd try on my own but foiling is gay.

Please just go ahead and fail your summer class already, you are completely incompetent.

I should just plug in 1 for x - right?

No limit exists - right?

do some algebra on that expression to simplify it and then see

Take (t - 1)^2 out of the radical:

Lim t -> 1+: [(t - 1) / (7t - 7)] * sqrt(t + 9)

The limit on the fraction results in 0/0, so use L'Hopital's Rule to resolve it:

Lim t -> 1+: (1/7) * sqrt(t + 9)

= sqrt(10) / 7

HOW THE NIGGER FUCK IS THIS THE CASE?

How can you have these homework problems and not know what the rules are?

L'hôpital's rule

lol nvm

im gonna need to stare at that explanation for a while now.

With your type of problems it seems like you can just replace t with the number under lim and type that out in a calculator

Please improve yourself OP. Otherwise you'll sink.

Assuming I haven't already sunk rather far.

You're a fucking idiot. Literally die

I am and should.

...

If the dude can't even plug a number into an expression, then I doubt that he can evaluate derivatives.

Why use L'hospital? It's easier without using it.

OP obviously didn't read his textbook

Protip OP: Read your textbook
