Can you help me step by step?

Step 1

** **

**Differentiate f(x) wrt x and find f '(x)**

** **

Step 2

Now **equate f '(x)=0** and **find x to get the critical points**

Step 3

**Calculate value of f(x) at critical points** and at closed intervals i.e**. x = 3,4,8,9**

f(x) is absolute minimum at x = 4 an...
