2. ### Please double check my work

for #3) Can I do y' = (3x^4-9x^3+12x^2+3x) / (x^3+1)^2 y' = 3x(x^3-3x^2+4x+1) / (x^3+1)^2 ? for #5) Can i do h'(x) = 1/2(3+2x)^(-1/2)(2) h'(x) = (3+2x)^(-1/2) ? Im not sure about 10 and 12 it seems like something could be done or? TRhanks again guys i really appreciate it
