Answer & Solution

Correct Answer

(D) \(3\)

Step-by-step Solution

Detailed explanation

\(3-x \leq y \leq \sqrt{9-x^2}\) Points \(( p , p +1)\) lies on \(y = x +1\) So point of intersection between \(y = x +1 y =3- x \text { is } x =1, y =2\) and point of intersection between \(x+1=\sqrt{9-x^2}\) is \(x=\frac{-1+\sqrt{17}}{2}\) Hence…
