Answer:

-24

Step-by-step explanation:

The input is x because it is the independent variable.  The output would be y because it is dependent

y=-4x^2-8

y= -4 (2)^2-8

y= -4 (4)-8

y= -16-8

y= -24

Answer: The correct option is 4.

Step-by-step explanation: The given relation is: y=-4x^2-8. We have to find the values output if input is 2.

Substitute x=2 in the given relation.

y=-4(2)^2-8

Solve the above equation.

y=-4(4)-8

y=-16-8

y=-24

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