Answer:
[tex] f ( x ) = 2 . 2 5 ( 1 + 0 . 4 ) ^ x [/tex]
Step-by-step explanation:
We are given that the price of gas started at $2.25 and increased at a rate of 4% per year.
We are to write a function which models this situation using numerical values of A and r into the expression.
A = $2.25
r = 4%
Assuming x to be the time in years, the function would be:
[tex] f ( x ) = 2 . 2 5 ( 1 + 0 . 4 ) ^ x [/tex]
