For his services, a private investigator requires a $700 retainer fee plus $75 per hour. Let x represent the number of hours the investigator spends workir (a) Find a function f that models the investigator's fee as a function of x. f(x) = (b) Find f-1. x – 700 75 f1(x) = What does f1 represent? O f1 represents the amount in dollars paid for x numbers of hours of investigation. O f1 represents the amount in dollars paid beyond the retention fee for x numbers of hours of investigation. O f1 represents the number of hours of investigation the investigator spends on a case for x dollars. O f1 represents the maximum number of hours of investigation the investigator will spend on a case. O f represents the amount paid per each hour of investigation. (c) Find f-(1375). F(1375) =
