F (x) = (3x - 2). find f^-1f (10)

f-¹f(10)=10

Solution given:

f(x)=3x-2

let

y=3x-2

interchanging role of x and y

x=3y-2

y=

so

f-¹(x)=

now

f(10)=3*10-2=28

now

f-¹f(10)=f-¹(28)==10

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
