4 cards from this section. Quick, good the night before a test.
Define a critical point.
Think about where the slope of the function changes.
What is a local minimum?
Consider the lowest valley in a hilly terrain.
What is a critical point?
Think about how we identify flat spots or breaks in the graph.
A local maximum is defined as what?
Visualize a hilltop when the slope changes.
Given the function f(x) = x^2 - 6x + 8, find the critical points and classify them using the derivative tests. What does this tell us about the graph?
Check the second derivative at your critical points to understand concavity.
For the function f(x) = 4x - x^2, determine the dimensions that maximize the area of a rectangle given a perimeter. What mathematical principles apply here?
Utilize your knowledge of optimization through derivatives!
