Problem
1. Differentiate the function y = x3 + 60x.
2. What is the slope of the function y = 12 + 0.5x4 when x = 5?
3. Derive a formula for the slope of the function y = 4 + 4x-1 - 4x.
4. What is the slope of the function y = 4x0.5 when x = 4?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
