The function has a relative maxima at .
The function is incrementing on both sides.
The function's slope at cannot be determined.
The function has a relative minima at .
Which type of extremum does a relative (local) minimum represent?
No extremum
Overall minimum value of a function
Maximum value in a certain interval
Minimum value in a certain interval
At which type of critical points does imply has neither maximum nor minimum value?
Absolute extremes in isolated intervals where but doesn't change sign.
Relative maximum points where changes from positive to negative.
Points of inflection where or does not exist and .
Relative minimum point where changes from negative to positive.
What does it indicate if the derivative is positive on both sides of a critical point?
The function is always increasing

Point is an inflection point of .
Point has no significance to the graph of .
If the function has a critical point at , and the sign of the first derivative changes from positive to negative as increases through 3, what does this indicate about at ?
It implies an inflection point at .
It suggests a local minimum at .

Given that the first derivative of function changes from positive to negative at , what can be inferred about function at this point?
There is likely a local minimum at
There is likely a local maximum at
There is neither a local maximum nor minimum at
The behavior of function cannot be determined without further information.
Given that and that there exists an interval around where only when , what can be said about ?
It could be neither a maximum nor minimum since does not guarantee an extremum
It is likely a point of inflection since signifies concavity change
It is likely a local maximum since the second derivative test indicates concave down
It is likely a local minimum because suggests so
What is the purpose of graphing the function when using the First Derivative Test?
To calculate the derivative of the function
To visually inspect the critical points
To find the relative extrema directly
To determine the intervals of increasing or decreasing
