A third-degree polynomial has a positive coefficient for its x3 term. Its graph passes through the points (−1, −5), (0, 3), and (2, 8). What is the end behavior as x→∞? y→∞y rightarrow infinity

y→0y rightarrow 0

y→−∞y rightarrow negative infinity

y→−x

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

any options?
