Question 1
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?
💡 Hint: Check the second derivative at your critical points to understand concavity.
Question 2
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?
💡 Hint: Utilize your knowledge of optimization through derivatives!
