Use the given graph to determine the limit, if it exists.
A coordinate graph is shown with a horizontal line coming from the left crossing the y axis at four and ending at the open point 2,4, a closed point at 2,1, and a horizontal line starting at the open point 2, negative 4 and continuing to the right

Find limit as x approaches two from the left of f of x. and limit as x approaches two from the right of f of x
