Question

What is the range of the function: y=radical x-1 ?

Answer 1

\[y=\sqrt{x-1}\]

Answer 2

can you get a negative result from pluggin in an element of the domain?

Answer 3

Sorry, the question was "What is the range of the function \[y=\sqrt{x-1} where x \ge1 ?\]

Answer 4

\[x \ge 1\]

Answer 5

right and I'm asking sqrt(x-1) <---will this ever be negative for any element of the domain?

Answer 6

uh... I'm not sure about that, sorry. ;_;

Answer 7

Let's think about
y=sqrt(x)
the domain is x>=0
but if I plug in any number from that set y is never negative
it is only 0 or positive
