BQ6: Unit U Concepts 1-2

1. A continuity is predictable; has no jumps, breaks and holes; and can be drawn without lifting a pencil. A discontinuity is an interruption in a graph. 

2. A limit is the intended height of a function. A limit exists when the limit and the value, the actual value of the function, are the same.

3. We evaluate limits numerically with a table, graphically by tracing the ends of a graph, and algebraically  is direct substitution.
