From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!
Just like in Algebra I, we'll be introduced to brand-spanking-new functions. Some of these will be familiar (linear functions) and some won't (crazy quadratic and exponential functions). As all new things in math, remember that these functions are new for everyone. Learn to love them, and they'll help you get through yet another level of math with flying colors.
