convert degrees to celsius

Question

To convert from x degrees Celsius to y degrees Fahrenheit, we use the formula f(x) =   
                           __9__x +32

                              5

 Find the inverse function, if it exists. (If an answer does not exist, enter DNE.)

 

f −1(x) =____________

Answer 1

               Hi Jil here is the Temperature

 

 

             F=    C      x      9     +   32

                                   ___                                        

                                    5                                       

 

                             OR:                                    

 

 

                 F=     C    x     1.8    +32

 

 

             

                 C=     (f   - 32)

                         _________

                             1.8                                                          

 

 

                 C=     (  F-32) x   5/9              ***  9/5  =  1.8   *****

 

 

 

 

              f -1 (x)  

 

 

         =    1

              __  

              X
