Fundamentals of Differentiation
If is differentiable on and continuous on , at which point in the open interval does according to the Mean Value Theorem?
At the endpoint, or .
The specific value of cannot be determined without additional information about the function.
For all points such that .
At the midpoint, .
What is the value of the derivative of the constant function for all values of x?
Undefined
Depends on the value of x
If a function is differentiable at a point, it must also be:
Constant at that point
Continuous on most of the domain
Discontinuous at that point
Continuous at that point
Which of the following statements correctly defines differentiability?
A function is differentiable at a point if its integral exists at that point
A function is differentiable at a point if its derivative exists at that point
A function is differentiable at a point if its limit exists at that point
A function is differentiable at a point if its limit is equal to zero at that point
If is differentiable at , which of the following must also be true?
The derivative .
The graph of has a corner or cusp at .
The function has a maximum or minimum at .
is continuous at .
A particle’s position on the x-axis is given by , with velocity and acceleration . Given that and changes sign around while near , what can we conclude about ?
s(t) has a local minimum at t=2.
There is a gap in the graph of s(t) at t=2.
The graph of s(t) has a vertical tangent at t=2.
s(t) is discontinuous at t=2.
Given that exists for some real-valued function , what can be concluded about the behavior of this limit?
This condition only ensures continuity of f but not necessarily differentiability.
Existence of this limit implies there are no critical points for f near .
This limit guarantees that the second derivative of f exists and is finite.
This limit defines the derivative of at and confirms its differentiability there.
