Q6: Celsius and fahrenheit temperatures When the celsius temperature is Odegree,the corresponding Fahreneit temperature is 32 degree.When the celsius temperature is 100degree,the corresponding Fahreneit temp[erature is 212degree.Let C represent the celsisus temperature and F is the fahreneit temperature.
(a) Express F as an exact linear function of C.
(b) Solve the equation in part(a) for C,thus expressing C as a funtion of F.
(c) For what temperature is F=C?
