QUOTIENT RULE
I. Find the derivative of the following functions below using the quotient rule. Show your complete solution.
- "\\frac{x^2-7x}{2x^3+5x^2}"
- "\\frac{3x^2+7x-14}{x^3-4x^2}"
- "\\frac{2x^3+8x^2}{x^2+6x^2-10}"
II. Create your own given problem involving quotient rule and solve. Show your complete solution. Do not copy the given example below.
1. Example must have two different terms in numerator, and three different terms in denominator
eg. (do not copy)
y= "\\frac{8x^2-3x}{x^2+6x^2-10}"
2. Example must have three different terms in numerator, and three different terms in denominator
eg. (do not copy)
y= "\\frac{x^2+8x^2-3x}{2x^3+6x^2-10}"

Calculate the volume of a 0.750M H2SO4 solution containing 0.120 mol of solute.
Write a program that inputs three integers from the keyboard and prints the sum,
average, product, smallest and largest of these numbers. The screen dialog should
appear as follows:
Input three different integers: 13 27 14
Sum is 54
Average is 18
Product is 4914
Smallest is 13
Largest is 27
Write a program that asks the user to enter two integers, obtains the numbers from the
user, then prints the larger number followed by the words “is larger.” If the numbers
are equal, print the message “These numbers are equal.”
