11. Sketch a graph of the polynomial function described. fis increasing when -2 < x < 0 and x > 2;f is
decreasing when x < -2 and 0 < x < 2.
f(x) > 0 when x < -3, -1 3;
f(x) < 0 when -3 < x < -1 and 1 < x < 3.
one

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
