If f(x) = square root of x and g(x) = x + 1, then:(adsbygoogle = window.adsbygoogle || []).push({});

1. What is f+g(x)?

2. Domain of f+g(x)?

3. What is f(g(x))?

4. What is the domain of f(g(x))?

I put:

1. square root of x + x + 1

2. x >= 0

3. square root of x + 1

4. All real numbers?

Thanks.
