(Math 152A Supplement for 4.6)

 

Find the domain of the following functions (hold your mouse on the yellow rectangles for the solution to the odd problems).

1)                3                   2)                   5                   3)    
       y  =                                    y  =                                   y  =  3x - 7
                    x                                       x + 1

 1) x not equal to zero         

2)   {Real Numbers}     

3)   {Real Numbers}                          

 

4)                 4x                   5)                    5x                6)    
     y  =                                           y  =                                y  =  x2 - 3x + 4
                  2x + 3                                     7x - 1

4)     x not equal to 1/7                                                                   

5)     x not equal to 1/7       

6)     x not equal to 1/7                                                                                                                               

 

7)    y  =  3x2 - 5x + 2         8)               9)            

7)  {Real Numbers}           

8) {x | x >= 3}
