this week I learned about how to graphing reciprocals of quadratic functions.  With one vertical asymptote and with two vertical asymptotes.

last week I learned about solving absolute value equations, we were solving by graphing. Graphically for algebraically linear and quadratic. We need make a graphing to solve the equation.

This week I learned about how to solving systems of equations graphically. It’s mean when 2 or more equations are needed to find a solution.

this week I learned about quadratic inequalities, this is brand new for me. It has greater- than and less-than in inequality. And how to graphing quadratic inequalities, ugly line and perfect line. And add (0,0) to find out which side is it.

I didn’t learn anything this week，but I reviewed what I learned before. Such as Sequences and series, Absolute Value and Radicals and Quadratic equations, etc.

this week I learned about how to solving problems with Quadratic functions, some problems can be solved by writing,  Then graphing a quadratic function. And determining maximum or minimum related to operations with numbers. And modeling a problem for maximizing profits.

This week I learned about how to find out vertex, and how the graph looks like.
