Answer 7

@nikkixmaire

it states that f is the function for the percent battery life remaining and a is the number of minutes

therefore: f(22) is the function at a = 22 minutes, so this represents the percent battery life after 22 minutes

f(a) = 55 represents the minutes, a, where the battery is at 55% remaining
