You can observe the fand relate it with the definition of modulus function. Just recall absolute value function, it is x when x is greater than or equal to 0 and -x otherwise. Here, observe both the absolute values of x-3 and x-4. These values will be different in three intervals that is when x is less than 3, x is in between 3 and 4 and when x is greater than 4. Accordingly three cases have been taken.
Also, please correct the course code, it is BMTC 131.
