  • WE CAN USE THE VERTICAL LINE TEST TO TEST IF IT IS THE GRAPH ABOVE IS A FUNCTION OR NOT.
  • IF THE VERTICAL LINE IS DRAWN ACROSS THE GRAPH AND IT TOUCHES THE GRAPH ONCE IT MEANS THE GRAPH IS A FUNCTION.
  • IF IT TOUCHES THE GRAPH IT MEANS IT IS NOT A FUNCTION.

IN THE ATTACHED PICTURE YOU CAN SEE THE YELLOW VERTICAL LINE TOUCHED THE GRAPH ONCE IT MEANS THE GRAPH ABOVE IS A FUNCTION.

THEREFORE THE LAST OPTION IS THE SOLUTION. THE GRAPH IS A FUNCTION BECAUSE IT PASSES THE VERTICAL LINE TEST .

HOPE THIS HELPS
