Answer:

The correct option is 4.

Step-by-step explanation:

The given relation is

[tex]y=-4x^2-8[/tex]

We have to find the values output if input is 2.

Substitute x=2 in the given relation.

[tex]y=-4(2)^2-8[/tex]

Solve the above equation.

[tex]y=-4(4)-8[/tex]

[tex]y=-16-8[/tex]

[tex]y=-24[/tex]

The value of output is -24 at x=2. Therefore the correct option is 4.
