Find the following.
2. {a, e, i, o, u} union {a, b, c, d, e}

3. {a, e, i, o, u} intersect {a, b, c, d, e}

4. |{a, e, i, o, u}|

Step-by-step explanation:

1. {a,e,i,o,u,a,b,c,d,e}

2. {} none

3. {a,e,i,o,u}

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

something over 10 so ? /10
