Using the same function as in Question #3 ( f(x) = 4x – 3 ), determine the value of x when:

 

f(x) = – 7       

 

 f(x) = 13

 

f(x) = 57

f(x) = -7        soooo        -7 =  4x-3

                                       -4  = 4x

                                         x = -1

 

I think you can now do the others !  cheeky
