Use the given graph to determine the limit, if it exists. A coordinate graph is shown with a horizontal line crossing the y axis at six that ends at the open point 2, 6, a closed point at 2, 1, and another horizontal line starting at the open point 2, negative 2. 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. . (7 points)
