Question

F(x)=2x and g(x)=square root of x what is the domain of f(g(x))?

Answer 1

It is C) X_>1

Explanation:

Just took it on edge

Answer 2

`x\ge 0`

Explanation:

The given functions are:

`f(x)=2x`

and

`g(x)=√(x)`

Now,

`f(g(x))=f(√(x) )`

`f(g(x))=2√(x)`

The domain refers to values of
`x` for which
`f(g(x))=2√(x)` is defined.

The expression under the radical sign must not be negative.

The domain is

`x\ge 0`
