Question

dx
8.) Write the value of the derivative of f (x) = |x-1| + x - 3) at * = 2​

Answer 1

Step-by-step explanation:

Correct option is

A

0

Consider the given function.

f(x)=∣x−1∣+∣x−3∣

Since, x=2⇒∣x−1∣=x−1 and ∣x−3∣=−(x−3)

f(x)=(x−1)−(x−3)

f(x)

1−x

If f(x)=

2−e

1/x

x(3e

=0

=0, x=0,

Answer 2

Step-by-step explanation:

f(x) =(x-1)+(x-3)

f(x)=2

ie,(2-1)+(2-3)

=1+(-1)

=0
