1. Find \( f''(x) \) for the following functions.

   (a) \( f(x) = \frac{1}{x^2} \)
   
   \[ f''(x) = \underline{\hspace{5cm}} \]

   (b) \( f(x) = x^{3/2} - 5x \)
   
   \[ f''(x) = \underline{\hspace{5cm}} \]

   (c) \( f(x) = (x^3 + 2x)^6 \)
   
   \[ f''(x) = \underline{\hspace{5cm}} \]

   (d) \( f(x) = \frac{3x + 1}{2x - 3} \)
   
   \[ f''(x) = \underline{\hspace{5cm}} \]

Expert Solution
Step 1 As per guidelines we are solving 1st 3 sub-parts.

Given:

 a) fx=1x2

            =x-2

      f'(x)=ddxx-2

  Apply power rule xn'=n·xn-1

              =-2x-2-1

               =-2x-3

                  =-2x3
