Answer 9

Ben shared his post with 2 friends. Each of those friends shares with 3 more every day, so the number of shares triples every day.

Answer 10

so the pattern is 2, 6, 18, 54, .....

initally ben has 2 friends

f(x) = 2(a)^x a is the base and x is the time.... in days

so if things triple, what number do you think will be the base..?

Answer 11

for carter, the pattern is 10, 20, 40, 80, .....

so g(x) = 10(b)^x b is the base and x is the time in days

so what do you think the base is for this problem if its doubling..?

Answer 12

I know carter is 10 (2)^x

Answer 13

So for ben it would be 10(3)^x

Answer 14

right @campbell_st

Answer 15

the base is 3... but its not 10 in front.... go and look at what I posted for Ben

Answer 16

sry 2(3)^x

Answer 17

that would be my answer...

when x = 0 which is the initial time, ben has 2 friends f(0) = 2*(3)^0 = 2
