Key Attitudes
Math is about using what you know to create something new.
Key Ideas
A limit can be thought of as the value a function approaches.
Limits can be determined graphically, numerically, or algebraically.
When evaluating limits algebraically, first substitute the value and see what happens. If you get an indeterminate form, then you re-write it using algebra so that it is not an indeterminate form.
Key Skills
I can explain the meaning of a limit of a function.
I can determine the limit of a function using a graph, a table of values, or algebra.
