find the numerical value for W such that L hopital rule applies to the following limit then compute value L of that limit lim x--3 4x^(2)-10x +W/x-3 =L

Question

find the numerical value for W such that L hopital rule applies to the following limit then compute  value L of that limit  lim x-->3  4x^(2)-10x +W/x-3  =L

tkhunny · Answer

If you mean $\dfrac{4x^{2}-10x+W}{x-3}$?  That is NOT what you have written.

tkhunny · Answer

$\lim\limits_{x\rightarrow3} (x-3) = 0$

Find $W$ so that: $\lim\limits_{x\rightarrow3} (4x^{2} - 10x + W) = 0$

anonymous · Answer

so will W be 6

anonymous · Answer

-6

raden · Answer

agreed ^^

tkhunny · Answer

That will do, if I have translated the expression correctly.

anonymous · Answer

but -6 is wrong

anonymous · Answer

what happened to L? This function is equal to L.

tkhunny · Answer

Did you answer the question?  Is asks for the limit, not just the value of W.

tkhunny · Answer

Ever graph a Rational Function?

anonymous · Answer

how do you find L?

tkhunny · Answer

You didn't answer my question.  I'm trying to answer yours.

anonymous · Answer

i got it it. i factored the top function and which will cancel x-3 in the denominator. thanks!

tkhunny · Answer

Good call.  Does the problem statement DEMAND that you use l'Hopital's Rule?
