Howdy, just a quick question,
y = 4x/(square root (x+1)
I have to find y' and y''
I have this as my y'
4(square root(x+1) - 2x/(square root x+1) all of this divided by x+1
I can show my work if you want but it's just tedious writing it out on this, I can show it though if you like. (If my y' is wrong that is)
My question is for y'' do I have to use product rule on the 4(square root x +1) then a quotient rule on 2x/( square root x+1) and then another quotient rule for the overall derivative? BLAH, I want to know if I'm over doing it or if it really is the right process.
Thank you as always.
