Which system of inequalities is graphed below

Option D

Step-by-step explanation:

Let's explain why the Option D is correct :

This is a parabola equation with vertex at x = -8.

Despite that the "traditional equation" is  in this case  the parabola equation is plotted in the X axis and has a sign which indicates that X will take values less and equal than

The graph of the parabola is attached to the answer.

This is a hyperbola equation with center at (0,0) and vertex's : V1=(3;0) and V2=(-3;0)

The two points (0;5) and (0;-5) on the Y axis are not on the hyperbola.

It's similar to the previous case of the parabola, Despite that the "traditional equation"  of the Hyperbola :  in this case  the hyperbola  equation has a sign which indicates that hyperbola will take values greater than those who correspond to

The graph of the Hyperbola is also attached

Finally we deduce  that the  D system of inequalities is the correct one.

Also the answer is attached.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

huh? im pretty sure it is in 199
