question of differentiation​

Answer 1

which classQ is thid

Answer 2

Answer:

ans should be 0

Step-by-step explanation:

When x belongs to (1,5) you can clearly see that

x-1 > 0 and x-5 < 0

So according to definition of modulus operator we see that |x-1|+|x-5| converts to-

+(x-1)-(x-5) = 4

Hence the expression reduces to 4

So the derivative is 0.
