Answer:
The value is: [tex]4[/tex]
Step-by-step explanation:
You have the following expression:
[tex]-2x^2+4y[/tex]
The exercise provides you these values of the variables "x" and "y":
[tex]x =-2\\y = 3[/tex]
Then, in order to find the value of [tex]-2x^2+4y[/tex], you need to substitute the given values of the variables into the expression.
Therefore, its value is:
[tex]-2x^2+4y=-2(-2)^2+4(3)=-2(4)+12=-8+12=4[/tex]
