4*x^3 - 8*x
Detail solution
  1. Differentiate 4x38x4 x^{3} - 8 x term by term:

    1. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: x3x^{3} goes to 3x23 x^{2}

      So, the result is: 12x212 x^{2}

    2. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: xx goes to 11

      So, the result is: 8-8

    The result is: 12x2812 x^{2} - 8


The answer is:

12x2812 x^{2} - 8
