What does it mean for a graph of a function at a certain point if the second derivative at that point is positive?
The function has an inflection point at that location.
The graph is concave down at that point.
The function has a maximum value at that point.
The graph is concave up at that point.
If for all in an interval, which of the following must be true about on that interval?
The function is increasing at a decreasing rate on that interval.
The function is concave up on that interval.
The graph of the function has a horizontal tangent line at some point in the interval.
The function has no points of inflection on that interval.
How does connectivity of a function influence the behavior of its derivatives?
A continuous function ensures the derivatives also exhibit continuous behavior.
The derivatives must be discontinuous where the original function has jumps.
The derivatives will have vertical asymptotes where the original function is continuous.
The continuity of the original function does not affect the derivatives in any way.
If a function is increasing on the interval , what must be true about its first derivative on that interval?
The sign of cannot be determined.
Suppose a particle’s position along a line is given by . At what value(s) of t does the acceleration change signs?
At .
At .
There are no values of t where acceleration changes signs.
At .
If , what behavior does this suggest about g(t) as t approaches zero from positive values?
g(t)'s rate remains constant as t approaches zero from above.

g(t)'s rate of change increases without bound as t approaches zero from above.
Incorrect implication indicates limitless growth negative direction leading towards infinite decrease instead increase suggested correct answer.

Given that a particle moves along a straight line with velocity given by a differentiable function , where represents time, which statement must be true about at a point where the acceleration is zero?
The first derivative of , representing acceleration, equals zero but could change signs before or after this point.
The second derivative of equals zero indicating an inflection point for velocity.
The value of itself is necessarily at its maximum or minimum.
The first derivative of equals zero and must remain constant before and after this point.
If and , then which of the following must be true?
Nothing can be concluded regarding extrema or points of inflection without additional information on higher derivatives beyond just
indicates that is definitely where either global or local minima occur since suggests upwards concavity around .
is definitely an inflection point because implies a change in concavity there.
could be an inflection point or nothing particularly noteworthy in terms of maxima/minima because only knowledge about isn't sufficient to determine the behavior of .
Given that a continuous function has a derivative everywhere except for where there is a sharp corner, how does this affect the graph of its second derivative, ?
There will be a hole in the graph of when .
There will be no graph for when since doesn't exist there.
There will be a vertical asymptote on the graph of when .
There will be no change to the graph of as it crosses since corners don't affect second derivatives.
