Range of ✓x-1?

1 Answer

If the function given is sqrt{x}-1
\text{Range}=[-1\ ,\ infty)

If the given function is sqrt{x-1}
\text{Range}=[0\ ,\ infty)

Explanation:

Range is defined as the values of the dependent variable for which the function is defined.

The radical function of the form c\sqrt{ax+b}+k has range f\(x)\ge k

So, if our given function is \sqrt{x}-1, the range would be:

f(x)\ge -1

And, if our give function is \sqrt{x-1}, the range would be:

f(x)\ge 0

That's it!
