Use the Desmos graph Limits and Continuity: Informal to answer the following questions. Drag the blue point currently located at $\displaystyle {\left({7},{3}\right)}$ to $\displaystyle {\left({7},{1}\right)}$. You may also use the numerical slider for $\displaystyle {b}$.

After making this adjustment to the Desmos graph, the numerical value of the limit at $\displaystyle {x}={7}$ is
$\displaystyle {y}=$Preview Question 6 Part 1 of 3  

After making this adjustment to the Desmos graph, the value of the function at $\displaystyle {x}={7}$ is
$\displaystyle {y}=$Preview Question 6 Part 2 of 3  

By using the slider for $\displaystyle {x}_{{0}}$ or dragging the red point currently located at $\displaystyle {\left({5},{2}\right)}$, explore the graph as $\displaystyle {x}$ increases from 5 to 8. Is the function continuous at $\displaystyle {x}={7}$? ? no yes
