Differentiate each function

a) y = -3x^2 + 5x - 4

b) f(x) = 6/x - 3/(x^2)

c) f(x) = (3x^2 - 4x)(x^3 + 1)

thank you in advance :)

  • Calculus -

    Now wait a minute, you try first.

  • Calculus -

    is it

    a) y'= -6x + 5

    b) f'(x)= -6/x^2 + 6/x^3

    c) f'(x)= 15x^4 + 6x - 16x^3 - 4
