**Calculus**

the first 2 is centered on the division line which has x-2/(sqrt2)-2. I think I placed the brackets right??
*February 13, 2011*

**Calculus**

No it only has the sqrt x. The -2 is outside of the sqrt. Just so I know. Had it all been under the square root would I have multiplied the top and the bottom by that sqrt(x-2)?

The problem is lim --> 2 for g(x) which is 2((x-2/(squareroot x)-2)) I just substituted 2 in for x and 2((2-2)/(squareroot 2)-2) = 0 This doesn't look right. It seems like I'd need to try something different. Can someone tell me if it's right or wrong? And if ...

I figured this out this way but am not sure it's right. f(2) + 4(2) = f(2) + 8. From this we can tell that it exists, but I'm not sure why.

This is what I tried. g(x) = 2((x-2/(squareroot x)-2)) lim --> 2 I just substituted 2 in for x and 2((2-2)/(squareroot 2)-2) = 0 This doesn't look right. It seems like I'd need to try something different.
*February 12, 2011*

**calculus**

Use the function given to answer the following questions. g(x)= 2 x-2/(squareroot x)-2 The first 2 is set in the middle of the division line. I think signifying that you solve the x-2/(squareroot x)-2 first then multiple everything by 2. problem to solve is lim-->2 g(x)
