Ataxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or f = $2.25 + $0.20(m - 1) where f is the fare and m is the number of miles. if juan's taxi fare was $6.05, how many miles did he travel in the taxi? if juan's taxi fare was 7.65, how many miles did he travel in taxi

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

Witch represents the inverse of the function f(x)=1/4x-12
