Step-by-step explanation:

You have the following expression:

-2x^2+4y

The exercise provides you these values of the variables "x" and "y":

$x =-2\\y = 3$

Then, in order to find the value of -2x^2+4y , you need to substitute the given values of the variables into the expression.

Therefore, its value is:

-2x^2+4y=-2(-2)^2+4(3)=-2(4)+12=-8+12=4
