How i do this i dont really know how to do this.

-1   |   1   4    4

Step-by-step explanation:

Changing to the root format x- k where k is the root

(x^2+4x+4) / (x- -1)

the outside is -1  and the inside is the coefficients of the terms

-1   |   1   4    4

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
