What is the union of the two sets a= [4,810,12,14] and b= [ 12,14]

Set B is a subset of set A so their union will be A = {4, 810, 12, 14}

need points to ask question

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
