1. The document is a math worksheet containing 5 calculus problems involving derivatives. 2. For each problem, the student set up the derivative using implicit differentiation and obtained the derivative expression. 3. The student provided the work and solutions for taking the derivatives of 5 functions: y = e(3x^2+7x), y = esin8x, y = (e^-6x - e^7x)^4, y = ln(6x^2 - 5), and y = 6(7x^2 + 9).
