Question

Asap Select the correct answer. Which function has a restricted domain?

Answer 1

Step-by-step explanation:

Check second one

$\\ \rm\Rrightarrow k(x)=(-x+3)^{\frac{1}{2}}$

1. 1/2 means square root

$\\ \rm\Rrightarrow \sqrt{(-x+3)}$

So

$\\ \rm\Rrightarrow -x+3>0$

$\\ \rm\Rrightarrow -x>-3$

$\\ \rm\Rrightarrow x$

Hence.

Domain is restricted

Option B is correct
