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 four that ends at the open point 2, 4, a closed point at 2, 1, and another horizontal line starting at the open point 2, -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..

Answers:
4; -2
