If A and B are any two disjoint sets then n(AnB)=
a)1
b)0
d)2
d)3

the answer is B. 0

Step-by-step explanation:

which means there is no common element in the set. so that's an empty set or 0

If A and B are any two disjoint sets then n(AnB) is equal to an empty set ∅ or {}

answer is b

i need the table so i can see

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
