What is the range of the function f(x) = -4|x + 1| − 5? A.
(-∞, -5]
B.
[-5, ∞)
C.
[-4, ∞)
D.
(-∞, -4]

A (-∞, -5]

Step-by-step explanation:

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

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
