y(x)=\left|\begin{array}{ccc}\sin x & \cos x & \sin x+\cos x+1 \\ 23 & 17 & 13 \\ 1 & 1 & 1\end{array}\right|, x \in R

, then

\frac{d^2 y}{d x^2}+y

is equal to:

View answer and explanation

Correct option: A

Option A (6) is correct because after finding the first and second derivatives of y(x) and then adding y and the second derivative, the result is 6.
