what is the pattern between these numbers?
x=0, f(x)=1
x=1, f(x)=3
x=2 f(x)=9
x=3 f(x)=27
x=4 f(x)=81
Thanks in advanced!

Alright...so it looks like...

everytime 'x' goes up 1....f(x) increases by a certain amount....

When x = 0....f(x) = 1
When x = 1....f(x) goes to = 3

Hmm we have an addition of 2? or maybe a multiplication of 3?

Lets keep going...

when x = 2...f(x) goes to 9

So if it was an addition of 2...this would be 3 + 2 = 5  .....

If it is multiplication by 3...we would have 3 x 3 = 9 ...which it is!
