Lesson Comments
We looked at graphs of polynomial functions and related their properties to the graphs. We looked at maximum and minimum points, turning points, intercepts, and intervals where they increase or decrease.
Graphs of quadratics are parabolas. Solving quadratic equations by factoring and completing the square were reviewed. Solving by graphing was also discussed.

Lesson Comments
We solved several systems using determinants and several using the inverse of a matrix and matrix multiplication. We discussed inconsistent and dependent systems. We did some spreadsheet math involving matrices.
Together, we prepped for Rachel’s quiz. She stated that she wanted to focus our time on inverse of functions.
We discussed what the inverse of a function is in principle.
We graphed a very basic example function and its inverse.
We worked on problems from her study guide trying to cover a variety of sections in our limited time. We covered about half the sections.
Rachel seemed to understand the concept well enough. However, she may have benefited from a more fluid mastery of the basics that needed to be performed in order to algebraically manipulate the inverse equation to solve for y.
