Analytical Applications of Differentiation
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.
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.
What conclusion can be drawn if for all values less than but approaching from both sides and for all values greater than but approaching ?
f(c) is an inflection point where concavity changes from down to up.
f(c)'s behavior suggests neither local extremum nor change in concavity based solely on these conditions.
f(c) is inconclusive regarding maxima or minima without further information on f'(c).
f(c) represents an absolute maximum given the change in concavity around this value.
If is twice differentiable on , which statement about must be false?
's second derivative might indicate points of inflection when transitioning from concave up to concave down or vice versa on .
could have jump discontinuities anywhere on .
's first derivative could have relative extrema provided by critical points where or undefined within .
's first and second derivatives may or may not exist simultaneously for all x-values.
Consider the exponential function , where represents the base of natural logarithm. What can be said about the relationship between its first and second derivatives?
The second derivative will always be positive, but the first may not be due to the constant of integration when integrating
The first derivative increases faster than the second since exponentially growing functions accelerate over time
The first derivative is inversely related to the second derivative due to its exponential growth nature
The two derivatives are the same because the exponential function is its own derivative
If , where and except where causing as well; considering exists everywhere excluding due to lack of smoothness caused by — what must hold true for near ?
q'' cannot exist at x=a.
q'' can be either negative or positive as long as the graph of p doesn’t show a point of inflection at a.
q'' must be positive at x=a.
q'' is negative x a not smoothness ensures concave down behavior.

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.
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 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 .
