x∇y = xy − y
Then 2∇3 = (2X3)- 3
6-3 = 3
Hence, B is the Answer
Then 2∇3 = (2X3)- 3
6-3 = 3
Hence, B is the Answer

Given that \(x∇y = xy − y\) and we need to find the value of \(2∇3\)
To find \(2∇3\) we need to compare what is before and after \(∇\) in \(2∇3\) and \(x∇y\)
=> We need to substitute x with 2 and y with 3 in \(x∇y = xy − y\) to get the value of \(2∇3\)
=> \(2∇3 = 2*3 − 3\) = 6 - 3 = 3
So, Answer will be B
Hope it helps!
