trying to work out some practice problems on derivatives but i've got a few that are getting me stuck. wondering if anyone here can help me out.
1. (3x^2 + 7) (x^2 - 2x + 3)
2. y = 5^(x-2) 5 to the x-2 power, not sure if i wrote that right.
3. f(x) = log(base 2) of (x^2/x-1)
2nd derivative problem
d2y/dx2: 1-xy = x - y
thanks, the answers would be nice but and explanation of how to work thru the problem is better.
