Answer 1

...........

Answer 2

domain and range plzz

Answer 3

reply plzzzzzz

Answer 4

Roots must be zero or positive. So at first 2 is > than 0 so ok. In the second root it must be \[1+x \ge0 =x \ge-1\] So the domain of the function is \[f(x)\in[-1,+\infty)\] As for the range of the function it is (sqrt2 +1 till +infinity)
