Answer:

the correct answer is option C because it is maximum at (0,-2)

Step-by-step explanation:

given equation,

y = -x² -2

to find maxima and minima we will differentiate the equation

[tex]\frac{\mathrm{d} y}{\mathrm{d} x}=-x^2-2[/tex]

[tex]\frac{\mathrm{d} y}{\mathrm{d} x}=-2x\\\frac{\mathrm{d} y}{\mathrm{d} x}=-2[/tex]

hence we can see that double differentiation is - ve so the equation will maximum.

hence, now putting value from option C

the value of y comes out to be -2

now, putting value from option D

value of y comes out to be -6

hence, the correct answer is option C because it is maximum at (0,-2)
