Question

what is the range of this function ?

Answer 1

\[f(x)=\sqrt{x+5}-\sqrt{x+1}\]

Answer 2

I think (0,2)

Answer 3

but I need a solution .

Answer 4

From 0 to 2 is the range

Answer 5

The domain of this function covers all of x's except those for which the function is forbidden. so it is x>=-1. For x = -1 you'll get a 2 but as x tends to infinity that is shown to get a zero though. so the range starts from 2 and ends up with a 0.

Answer 6

(0,2)
