Hi,
the idea is examining the ordered pairs (x,y) as listed for the function f(x) 
Given f(x) = {(2,3),(3,{{{highlight(7)}}}),(-1,{{{highlight(5)}}}),(0,-1)
 State the domain of f(x)    {2,3,-1,0}   || Allowable x- values
 State the range of f(x)     {3,7,5,-1}   ||  Allowable y-values
 Find f(3)= 7 
      f(-1)= 5
