+    <p>
+      This section is about limits, the behavior of a function's output value as the input value is getting closer
+      and closer (but not equal to) a specified number.  A function can be described by a graph, a table of values,
+      or by an algebraic formula, so we work on interpreting limits of functions described in graphical, numerical, and algebraic ways.
+    </p>
+    <p>
+      It would be helpful to practice how we can interpret information about a function from a graph, or from a 
+      piecewise description of a function.  Calculating an algebraic limit can also require us to use algebraic simplification
+      techniques such as factoring, combining rational functions using a common denominator, and rationalizing a radical function
+      using the conjugate.  
+    </p>
