Use set builder notation to describe these sets.

a) s1 = {1, 2, 4, 8, }
b) s2 = {2, 5, 8, 11, }
c) s3 = {1, 4, 9, 16, }
d) s4 = {a, b,c, d,e, f z}
e) s5 = {a, e,i, o,u}

a) S1 = { 2^x | x belongs to the set of Whole Numbers}

b) S2 = { 2+3(x-1) | x belongs to Natural Numbers }

c) S3 = { x^2 | x belongs to the set of Natural Numbers  }

d) S4 = { x | x belongs to English Alphabet }

e) S5 = { x | x is a Vowel of English Alphabet}

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}

answer is:

a). backstage view

explanation:

backstage view is the area where files and data about them is managed— creating, saving, printing, sending to others, inspecting for hidden metadata or personal information, and setting options. so in this way we can add many things to our document swiftly.
