Question

The domain of function $f\left(x\right)=(\sqrt{x-4}+\sqrt{6-x})$ is

• A. $(4,6\}$
• B. $[4,6]$
• C. $[4,6\}$
• D. none of these

Answer 1

The correct option is B $[4,6]$

$f\left(x\right)=(\sqrt{x-4}+\sqrt{6-x})$

As we know that if given for will be something like this.

$f\left(x\right)=(\sqrt{x-a}+\sqrt{b-x})$

Then its domain always $[a,b]$

So. $AC$ to question

$=[4,6]$
