The value x is approaching is the asymptote because the function goes closer and closer to that x value. What is indeterminate quotient form and how is L'hospital's rule used for it? And therefore, the limit DNE. It is approximated to be touching a curve at a single point. If they are the same, that is your answer.

What are the three rules for a limit to be continuous? An asymptote of a curve is a line such that the distance between the curve and the line approaches zero as they tend to infinity. Watch AP Calculus teacher Jamil Siddiqui, the Massachusetts Teacher of the Year 2019, explain graphical limits. Derivatives Circuit Answer Key; 5.2: FRQ Modules 1-4. If a function is defined only for a certain interval. So, if applied here it is a break in the continuity of a function. ⚡ Read- AP Calculus AB/BC: Squeeze Theorem. This works for functions like polynomial, logarithmic, and exponential. What happens if the one-sided portions of a limit do not match? That is, the graph can be drawn in 1 continuous motion without lifting your pencil. The graph would look something like this: As you can see, as the graph gets closer and closer to x, the y-value just keeps increasing exponentially.

Email Address. As the x value continues to increase and goes to infinity, the function will be getting closer and closer to k, but it won't cross it. AP Classroom Resources for Unit 1?- AP Calc AB. Basically, on a continuous interval. Limits that have a positive or negative sign at the top of the x value it is approaching are called single-handed limits. As you can see, the double-sided limit here does exist because the function approaches the same value from both sides at x. If you get an actual number, then that's your answer! AP Calculus AB. save.
