Question

Use set builder notation to describe these sets.

a) S1 = {1, 2, 4, 8, 16,...}
b) S2 = {2, 5, 8, 11, 14,...}
c) S3 = {1, 4, 9, 16, 25,...}
d) S4 = {a,b,c,d,e, f ,..., z}
e) S5 = {a,e,i,o,u}

Answer 1

a) S1 = x belongs to the set of Whole Numbers

b) S2 = 2+3(x-1)

c) S3 = x^2

d) S4 = x

e) S5 = x

Step-by-step explanation:

Whole Numbers = {0, 1, 2, 3, ...}

Natural Numbers = {1, 2, 3, ...}

English Alphabet={a, b, c, d, e, ... , x, y, z }

Vowels of English Alphabet = {a, e, i, o, u}
