Take \(2x + y^2\) = > 2(2) + 16 ( here x = 2 that is max value and since y is square we can take largest -ve i.e. -4).

Ans D

we can analyse the value of x and y:

x = - 3.....0.............2

y = -4......2.............3

Given

\(2x + y^2\)

See we have \(y^2\) that can make negative value to positive. So, highest value for y must be -4. For x we have to take positive value.

\(2x + y^2\)

= \(2*2 + (-4)^2\)

= 20

The best answer is D.
