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.

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