How to solve a 2nd derivative problem (business calculus)

By Songoku23

  • Find the 2nd derivative f''(x)

    f'(x)=9 goes to f''(x)=0; The derivative of 9 (which is a constant) is 0

  • Start with the given function

    f(x)=9x+2

  • Find the 1st derivative f'(x)

    f(x)=9x+2 goes to f'(x)=9; The derivative of 9x is 9 and 2 is a constant which is 0

  • The final result

    f"(x)=0
