Show that the poisson distribution belongs to the exponential family. note that if random variable y has a poisson(θ) distribution, then the probability function of y is given by

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
