Analytical Applications of Differentiation
What can be concluded about a continuous function , if any horizontal line intersects its graph more than once over an interval ?
There are no critical points for within .
The second derivative test fails to determine concavity over .
The function has neither strictly increasing nor strictly decreasing intervals on .
The derivative does not exist over .
What does it mean if the first derivative of a function is negative at a specific point?
The function is increasing
The function is decreasing
The function has a local minimum
The function has a local maximum
How does the First Derivative Test help determine local extrema?
By analyzing the sign changes of the derivative
By evaluating the function at critical points
By finding inflection points
By calculating the average rate of change
If for all in the interval except for at a single point where , how does this affect the monotonicity of on ?
It creates a maximum at , so is not increasing over the entire interval.
It does not affect; is still increasing on .
It indicates that there is a minimum at , creating a section where the function decreases.
The function has an inflection point at , changing concavity but not monotonicity.
On which of the following intervals must the function be decreasing?
Between the critical points where and changes from negative to positive
Between the critical points where and changes from positive to negative
Wherever its second derivative
When its first derivative satisfies
If the second derivative of function at point is positive and its first derivative at point is zero, what must be true about function near point ?
It has a local maximum at point .
It has a local minimum at point .
The function is constant near point .
It has an inflection point at point .
Assuming continuous differentiability, if a critical point occurs within an open interval and does not correspond to any extrema or inflection points of a function , what can one infer about 's behavior around this critical point?
The function likely maintains its direction of monotonicity through this critical point.
This would represent an undetected extremum due to computational error.
The critical point separates regions where 's derivative changes sign.
There must be an inflection point near this critical point shifting concavity.

If a function is defined by , where and is non-negative for all values of except at turning points, what is the relationship between the increase/decrease in before and after turning points?
The function is always increasing because the negative linear term only appears once so its effect is minimized
The function is always decreasing because the negative linear term appears twice so its effect is doubled
The function will decrease before the turning point and increase after the turning point since the exponential term is always negative
The function will increase before the turning point and decrease after the turning point since exponential growth dominates the negative effect of the linear term
If a continuous differentiable function has an absolute maximum at , what can be said about ?
It must be constantly equal to one for all values near .
It must be negative and decreasing rapidly.
It must be positive and increasing rapidly.
It could be zero or undefined.
What is the result of finding the derivative of a function at an absolute minimum?
The derivative will be a large positive number.
The derivative will be a large negative number.
The derivative must equal pi.
The derivative will be zero or not exist.
