Contextual Applications of Differentiation
Which statement best describes what happens at an inflection point on a curve represented by ?
At an inflection point, the slope of the function's tangent line is zero.
At an inflection point, the function reaches its maximum or minimum value.
At an inflection point, the function crosses its horizontal asymptote.
At an inflection point, the concavity of the function changes.
If a company's profit function is modeled by where represents years since opening, what would be indicated by finding that ?
Profits are increasing faster after 10 years than they were after 5 years.
Profits started to decrease after year 10.
There was no profit in year five and ten.
Total profits are higher after 10 years than after 5 years.
What does it mean when you find out that , with r being any real number?
Function g(t) must pass through point (t,r).
The second derivative of function g(t), denoted as , must also equal r.
The rate of change or slope of g(t) at any given time t corresponds to r.
Function g(t)'s graph forms an arc with radius r centered at t.
If the function represents the height of a balloon above the ground, what does the value of signify?

The acceleration of the balloon at time .
The rate at which the height of the balloon is changing at the moment when .
The height of the balloon above the ground when .
If the speed of a particle at time is given by , what does the limit represent?
The instantaneous rate of change of speed at time .
The average speed of the particle from time to time .
The total distance traveled by the particle from time to time .
The average acceleration of the particle over time interval .
What does the derivative of a function represent?
The rate of change of the function at a specific point
The maximum or minimum points of the function
The value of the function at a specific point
The integral of the function over a specific interval

If we know only one point where , where k is some constant number, what can we conclude about function ?
Nothing conclusive without more information about behavior around this point can be determined from this single fact alone.
The slope of f will remain constant everywhere since its derivative equals k at one point.
Function f has an inflection point where its first derivative equals k.
Function f must be linear because its derivative at one point is constant.
A cylindrical water tank's water level falls as water leaks out; if represents volume (water as function (height)), what does negative indicate?
Increase both volume, height.
Volume increases while height diminishes.
Water volume decreases as height decreases.
Water volume stays stable regardless of height magnitude.
