Question Alex started a new social media account, which he uses to post pictures of cute animals. On
the first day, he had only 8 followers. However, his account became popular very quickly and
his number of followers tripled every day. Identify the recursive function that gives the number
of followers he has after n days.
A) f(n)-
B) f(n)-
f(1) = 8
(n) = f(n-1)+3 if n >1
f(1) = 3
(n) = f(n-1)+8 if n>1
f(1) = 3
in) -8f(n-1) if n > 1
14 (1)= 8
sin)=3(n-1) if > 1
C) rin)-
D) f(n)

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

37 = ending with 7

unit's digit in the cube..3

56 = ending with 6

unit's digit in the cube..2

133 = ending with

unit's digit in the cube..7

hope it : ( : )

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
