Logarithmic Functions

                     Lesson 1

                                                                                                                                                                          

                                                            Problem:   The statement y = log25x is equals to?

                                                            

                                                            Solution    x= by if y=logbx               

                                                            Step 1:                                                                                                                                                             

                     

                                                            Solution    (where x > 0 and b is a positive constant not equal to 1)

                                                            Step 2:        Hence, x=25y                                                             

                                                                                         

                                                            Solution    Answer: x=25y

Step 3:                                                            

Complete                                                                   

                                                                                                                               

                                                             Try two practice problems:  

 

                                                                                Solve the following:       

 

A.

The statement y = log2x is equals to?

B.

Find the domain of  y = log(x + 12)
