You can  put this solution on YOUR website! Hi there, 
The function f(x) = 4x -2 
f(x)= 4x-2  
f(-1)= 4(-1) - 2 = -6 
f(0) = 4(0)  - 2  = - 2 
f(3) = 4(3)  - 2  = 10 
Hope this helps:-)

You can  put this solution on YOUR website! Hi dear, 
 To find f(-1),all that you are to do is to put x=-1 in the given function. 
  HERE IS THE WORKING: 
If f(x)=4x-2 
then, 
f(-1)=4(-1)-2 
      =-4-2 
      =-6 
Also, 
f(0)=4(0)-2 
    =0-2 
    =-2 
And for 
 f(3)=4(3)-2 
     =12-2 
     =10 
Therefore, 
f(-1)=-6 
f(0)=-2 and 
f(3)=10 
HOPE THIS HELPS. 
Best regards,
