Name:
Make sure you clearly show all work. You must complete each problem using
the method indicated.
1. (5 points) Use the product rule to find
dy
:
dx
y = (2x + 1)(6x8 − 4x)
2. (5 points) Use the product rule to find
dy
:
dx
y = (6x − 1)x−1
3. (5 points) Use the quotient rule to find
dy
:
dx
y=
6x − 1
x
space
4. (5 points) What do questions 2 and 3 tell you about the relationship between the product
rule and the quotient rule?
5. (1 point extra credit) Using only the rules from section 9.4 (covered in class on Monday),
dy
find dx
.
