I suspect you meant, "if \ =\ -3x\ +\ 4)
" or something similar. If that was the case, if you want to evaluate )
, then just substitute 
for 
wherever it occurs in the function definition, thus: \ =\ -3(a\,+\,1)\ +\ 4\ =\ -3a\ -\ 3\ +\ 4\ =\ -3a\ +\ 1)
However, only being able to go on what you actually wrote: \ =\ -3\ +\ 4\ = 1)
for any value of . That means that \ =\ 1)
also.
