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

Answer 1

2nd one

Explanation:

Here if we simplify

`\\ \rm\Rrightarrow (-x+3)^(1/2)`

`\\ \rm\Rrightarrow √(-x+3)`

So

• -x+3>=0
• -x>=-3
• x<=3

So domain is restricted

Option B

Answer 2

Therefore, option B is correct.

`\large\boxed{\sf y=\left(3x\right)^{(1)/(5)}-4}` Has infinity domain

`\large\boxed{\sf y=\left(-x+3\right)^{(1)/(2)}}` Has a domain x < 3

`\large\boxed{\sf y=-\left(x+8\right)^3 }` Has infinity domain

`\large\boxed{\sf y=\:\left(4x\right)^2-5}` Has infinity domain
