    ___    
2*\/ x  - 2
$$2 \sqrt{x} - 2$$
2*sqrt(x) - 2
Detail solution
  1. Differentiate 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: goes to

      So, the result is:

    2. The derivative of the constant is zero.

    The result is:
