Question

F(x)={(1+3x)^1/2 X is not equal to zero and X=0

Answer 1

Answer:

Correct option is

B

e

2

Given,

f(x)=(1+2x)

1/x

,x



=0

Since, f(x) is continuous at x=0

Therefore,

f(0)=

x→ 0

lim

f(x)

f(0)=

x→ 0

lim

(1+2x)

1/x

This is 1

∞

form.

Therefore,

f(0)=e

x→ 0

lim

(1+2x−1)×

x

1

f(0)=e

x→ 0

lim

(2)

f(0)=e

2

Hence, this is the answer.
