The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. The function below shows the relationship between f(x) and x:

f(x) = 10(1.3)x

Which of the following graphs best represents the function?

Answer 1

Can someone please help?

Answer 2

\[\large f(x)=10(1.3)^{x}\]
What is the value of f(x) when x = 0 ?

Answer 3

@happyfeet8040 Well what is the value of a number, say 13, to the power of zero?
\[\large 13^{0}=?\]

Answer 4

any number raised to the power of 0 = 1

Answer 5

So the value of f(x) is 10 when x = 0. Which of the graphs shows this?

Answer 6

use this to find f(x)

Answer 7

Graph B? :/

Answer 8

Wait, or D..
