finding surface area where curve x={2y-1}

I've done a CD for 1/(8y-4) and then a u substitution for {2y-1} to cancel a term, but that still leaves me with an y term in my new integral.

I know writing the whole answer out on a computer is tedious, so any suggestions on how to go about solving this would really be appreciated.

A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 12 m/s skates by with the puck. After 3.0 sec, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 4.0 m/s squared, how long does it take him to catch his opponent??

Answer is 8.2 sec.
How do you get that?

How do you find the domain of a derivative. I did a problem where i found the derivative of f(x)=.5x-1/3 and i got 1/2. Now how do i find the domain of "1/2".

Do I find the domain of the tangent line which has a slope of 1/2?

Thanks!
