Answer:  A ∪ B = {a, b, c, d}

               (A ∪ B) ∪ C =  = {a, b, c, d, e}

               B ∪ C =  = {a, b, d, e}

               (B ∪ C) ∪ A  =  = {a, b, c, d, e}

<u>Step-by-step explanation:</u>

A = {a, b, c}       B = {a, b, d}         C = {b, d, e}

Union means "to join" so combine the sets to form a union.

A ∪ B = {A & B}

         = {a, b, c & a, b, d}

         = {a, b, c, d}          <em>because we do not need to list a & b twice</em>

(A ∪ B) ∪ C = {(A ∪ B) & C)

                  = {a, b, c, d & b, d, e}

                  = {a, b, c, d, e}     <em>because we do not need to list b & d twice</em>

<em />

B ∪ C = {A & B}

         = {a, b, d & b, d, e}

         = {a, b, d, e}           <em>because we do not need to list b & d twice</em>

<em />

(B ∪ C) ∪ A = {(B ∪ C) & A)

                  = {a, b, d, e & a, b, c}

                  = {a, b, c, d, e}     <em>because we do not need to list a & b twice</em>

<em />

What does <br> f(x) – g(x) =
andrezito [222]

Answer:

(f - g) (x)

Step-by-step explanation:

Since (x) is common between them, you can bring it out. for example,

f(x) = x +1

g(x) = 2x + 3

f(x) - g(x) = x + 1 - 2x + 3

= -x + 4

(f - g) (x) = x + 1 - 2x + 3

= -x + 4
