Find the domain and range of y fx SolutionFrom the graph we
     Find the domain and range of y = f(x)   
  
  Solution
From the graph we can see there is hole at x=3 and no y values for x between 3 to 4.
 Hence domain is [2, 3) U [4,6].
 (domain - all the values lies on x axis )
 Range is all the values lies on y axis.
 minimum value is 1 and maximum value is 3
 Hence Range is [1,3].
