The document contains a set of mathematical exercises, including calculus problems, function derivations, and an application problem involving a cake factory's revenue and costs. Here's a summary of the key items:

1. **Derivatives of various functions**:
   - Simple functions like \( f(x) = x^2 \), \( f(x) = \sqrt{x} \), and more complex ones like polynomials and logarithmic functions (e.g., \( f(x) = \ln(x^2 - 3x + 2) \)).
   
2. **Cake factory revenue and cost analysis**:
   - The revenue function is given as \( r(x) = -3x^3 + 40x^2 - x + 245 \).
   - Average costs are only partially visible but involve determining the effect of increasing cake production by 50,000 units.

3. **Convexity/concavity** of functions**:
   - Functions like \( f(x) = 50x^3 - 75x^2 + 100 \) and \( g(x) = -25x^2 + 5 \) are used to analyze whether the graph is convex or concave.

Do you want me to work through specific problems or provide detailed solutions for these exercises?

Here are 5 questions related to the content:

1. What is the derivative of \( f(x) = \sqrt{x} \)?
2. How do you determine if a function is convex or concave based on its second derivative?
3. What is the marginal revenue if the cake factory produces 50,000 additional units?
4. How would the cost function change if production increased significantly?
5. Can the function \( h(r) = r^3 - 2r \) represent the revenue of a business? Why or why not?

**Tip**: When determining convexity or concavity of a function, always check the sign of the second derivative. Positive means convex, negative means concave.

How will the revenue and total costs of the cake factory be affected if production increases by 50,000 units?

Explore how increasing production by 50,000 units affects the cake factory's revenue and costs. Understand the use of revenue functions and calculus to analyze business decisions. Suitable for advanced calculus and business mathematics students.
