As a student, I am interested in how you are involved within the government. I wish to inquire about the committees that you currently served in, whether it is state or local. It will be very useful for me to study someone with a local perspective.
I also wish to find out about what types of bills you have submitted. These bills may pertinent towards my own studies, especially if they involve any of the local issues.

Thank you for your consideration.
Sincerely,
Your Name"

y=3x^3-2x
dy/dt=(9x^2)(dx/dt)-2(dx/dt)
When x= -2

=36(3)-6
=102
