4 cards from this section. Quick, good the night before a test.
Evaluate lim as x approaches 3 of (x^2 - 2x + 1).
Substitute x = 3 into the function.
Evaluate lim as x approaches 4 of (x^2 - 16)/(x - 4).
Factor the numerator and then substitute.
What is a limit?
Think about how the function behaves at a specific input.
True or False: If lim as x approaches c of f(x) exists, then f(c) must be defined.
Remember, limits refer to the behavior approaching a point.
Evaluate the limit: lim as x approaches 0 of (sin(x)/x). What does this tell us?
Use the squeeze theorem or L'Hôpital's rule if you are struggling.
Determine the limit: lim as x approaches 2 of (x² - 4)/(x - 2) and explain any necessary transformations.
Think to factor or use L'Hôpital’s rule.
