Consider the function represented by 9x + 3y = 12 with x as the independent variable. How can this function be written using function notation?

Its 12 U^U

Step-by-step explanation:

subtract 9x from each side

3y = 12 - 9x

divide by 3

y = 4-3x

f(x) = 4-3x

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
