Let \(M=\left\{A=\left(\begin{array}{ll}a & b \\ c & d\end{array}\right): a, b, c, d \in\{ \pm 3, \pm 2, \pm 1,0\}\right\}\). Define \(f: M \rightarrow Z\), as \(f(A)=\operatorname{det}(A)\), for all \(A \in M\), where \(Z\) is set of all integers. Then the number of \(A \in M\) such that \(f(A)=15\) is equal to. 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
