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]

Answer:

f(x)=2.25X(1+.04)^x
