(a)Find the sum of the series 3 + 6 + 11 + ...,to n terms

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 f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)
