Well, anyone who knows about wolframalpha.com could find the answer pretty quickly (provided they knew how to format it)

www.wolframalpha.com/input/?i=%28%282e^%28x-5%29%29-2%29%2F%28x-4%29+as+x+approaches+5

TL;DR use internet website, find answer to be 0.

Even faster is just knowing math.

Substitute x for 5

x-4 is 1, and anything divided by 1 is equal to itself

Then you have 2e^x-5
Well anything to the 0 power equals one

So now we have 2-2

Which is zero

thats not how you find the limit. it asks what the value is as x APPROACHES 5. you have to find the values around it because the actual point on a graph doesnt have to coincide with the rest of it

That's only when the point doesn't exist e.g. 1/0

That's for a very basic understanding limits. Here, let's do an example: 2-x as x approaches 2. What does that approach? 0 right? The substitution method makes your life infinitely easier in higher calculus. Limits are as a number gets INFINATELY CLOSE to x, what does it get INFINATELY CLOSE to the Y value?

I'm lazy, though, and I don't really like taking the time to do non-homework math outside of class. I think substitution falls into that area.

Excellent username, though.

the answer is o lol, you didnt even have to worry aobut the fraction being undefined lol

Whats the square root of radical? o.o
#5 to #2 - anon (02/06/2014) [-]
"Root" is related to the Latin word "radix" from which the word "radical" is also derived. I believe this is the connection you've been looking for.
