How would you graph the solution set of x - 6 < -3?
a. draw an open circle on -9 and shade to the left.
b. draw a closed circle on -9 and shade to the left.
c. draw a closed circle on 3 and shade to the left.
d. draw an open circle on 3 and shade to the left.
me this is the last

Option D.Draw an open circle on 3 and shade to the left.

Step-by-step explanation:

we have

Solve for x

Adds 6 both sides

The solution is the interval (-∞,3)

All real numbers less than 3

In a number line the solution is the shaded area at left of x=3 (open circle)

The number 3 is not included in the solution

therefore

Draw an open circle on 3 and shade to the left

(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
