Question

Use the given graph to determine the limit, if it exists. A coordinate graph is shown with a downward sloped line crossing the y axis at the origin that ends at the open point 3, 1, a closed point at 3, 7, and another horizontal line starting at the open point 3, -3. Find limit as x approaches three from the right of f of x..

Answer 1

For the limit approaching 3 from the right, you want to follow the line to the right of x = 3. From the graph you're describing it sounds like that's y = -3. $\lim_{x \to 3} f(x)=-3$

The RHS limit is -3 even though f(3) = 7
