In dire need of help with derivatives.

if f(x)=(x2+3x+6)3, find f'(x)
if f(x)=3^1/2 / t^5 (square root of three divided by t to the 5th power), find f'(x)
If f(x)=(3x+4)^–1 , find f(x) .

  • calculus -

    all of these is the power rule
    y= x^k
    y'=kx^(k-1)

    f(X)= (3x+4)^-1
    f'=-(3x+4)^-2 * 3
