Limits and Continuity
Given a function with two local maxima at and , which method would be most appropriate to determine the absolute maximum value of over the closed interval [1,6]?
Factor to identify possible maxima within the interval.
Apply L'Hôpital's Rule to solve for limits approaching maxima.
Use integration from to to find areas under curves.
Evaluate at critical points and endpoints then compare values.
m(x) represents the total amount of interest gained by a bank account, where x is the number of years. What does m(20) represent?
The total amount of interest gained by the bank account after 20 days.
The total amount of money in the bank account after 20 years.
The total amount of money in the bank account after 20 months.
The total amount of interest gained by the bank after 20 years.
If the velocity of an object moving along a straight path is given by , what is the total displacement of the object from time to ?
Which of the following is the same as the slope of the tangent line to a curve at a specific point?
Derivative
Change in Y
Integral
Y-value
Which rates of change depend on the concept of limits?
Both instantaneous and average rates of change
Neither depends on the concept of limits
Average rate of change only
Instantaneous rate of change only
Which describes why a continuous function does not guarantee differentiability at every point on its domain?
Differentiability depends on whether a graph has an endpoint which continuous functions do not have.
Continuous functions are always differentiable since they have no breaks or holes.
A continuous function may have sharp corners or cusps where there are no defined tangents.
Continuity means that all vertical tangents are possible making differentiability certain.
