Question

Discuss the continuity and differentiability of the function f(x)=e|x|

Answer 1

Answer:

hope it helps you

Step-by-step explanation:

f(x)=∣x∣+∣x−1∣

It can be written as

f(x)=

2x−1

x<0

0≤x<1

x≥1

At x=0

LHL=−2(0)+1=1

RHL=1

LHD=−2

RHD=0

Continuous but not differentiable on x=0

At x=1 LHL=2(1)−1=1

RHL=1

LHD=1

RHD=2

Continuous but not differentiable on x=1

Continuous everywhere in (−1,2) but not differentiable on x=0, 1 in (−1,2).
