The given equtaion is,
[tex]f(x)=\sqrt[]{x-3}[/tex]
to check if the given function is integrable on given interval,
the function is only defined for,
[tex]x\ge3[/tex]
the function is intergal in the abovedomain,
thus the answer is, the function is intergal in the following innterval.
[tex]\lbrack3,\infty)[/tex]
