Answer:

  4.5

Step-by-step explanation:

The value of x that makes f(x) = -3 is ...

  4/3x -9 = -3

  4/3x = 6 . . . . . . add 9

  x = 6(3/4) = 18/4 = 9/2 = 4.5 . . . . multiply by 3/4

f^-1(-3) = 4.5

<span>                                                             4x -5(1/5x-9)= -15 x
                                                             4x + x+45=-15x
                                                             5x +45 = -15x                                                                                                            45=-20x 
                                                              x=-45/20
                                                              x= -9/4
 
 y+9 =1/5x
   y      = 1/5(-9/4)-9
      y     = -189/20
