Answer 1

Given:

The functions are

`f(x)=x^2`

`g(x)=x+6`

To find:

The value of g(f(0)).

Solution:

We have,

`f(x)=x^2`

Putting x=0, we get

`f(0)=0^2`

`f(0)=0`

Now,

`g(f(0))=g(0)`
`[\because f(0)=0]`

`g(f(0))=0+6`
`[\because g(x)=x+6]`

`g(f(0))=6`

Therefore, the value of g(f(0)) is 6 and the correct option is B.
