Answer 2

Hey there!

Consider the exponential growth equation:

$f(x) = P(1 + r)^{t}$, where:

P = initial amount
r = interest rate (as a decimal, divide a percentage by 100 to get its decimal form)
t = years

All you need to do is plug in your given numbers:

P = 120
r = 0.10
t = x

Your final equation will be:

$f(x) = 120(1.10)^{x}$

Hope this helped you out! :-)
