Given f(2) = 12, which of the following could be an equation of the function?
a.
f(x) = 8x – 2
b.
f(x) = 4x + 4
c.
f(x) = 6x – 4
d.
f(x) = –4x – 4

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

Two cyclists 84 miles apart start riding toward each other at the same. one cycles 2 times as fast as the other. if they meet 4 hours later, what is the speed (in mi/h) of the faster cyclist?

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
