f(x)=(4x-1)/3 for x=-3                          Evaluate the function for the given value of x, and write as an ordered pair. This question is sooo confusing, pls explain :( got me tripping

f(x) =  ( 4x - 1 ) / 3

 

First let's evaluate the function for  x = -3 . To do that, replace every instance of  " x "  with  " -3 " .

 

f( -3 )  =  (4(-3) - 1) / 3

                                               Multiply  4(-3)  to get  -12 .

f( -3 )  =  ( -12 - 1 ) / 3

                                               Combine  -12  and  -1  to get  -13 .

f( -3 )  =  ( -13 ) / 3

                                               Now we don't need to keep the parenthesees.

f( -3 )  =  - 13/3

 

So...the value of the function when  x = -3  is  -13/3  .

 

And....ordered pairs are written like this:      (  x ,   f(x)  )

So......the ordered pair for this solution is:    ( -3, -13/3 )   smiley
