this week in precalculus 11 I learned about solving quadratic inequalities in one variable.

Here is an example:

For the midterm, I reviewed everything that I have learned till now. One thing that I was reviewing that was not blogged about previously is a common difference. Here is an example:

This week in pre-calculus 11 I learned about modeling problems with quadratic function. I was a little bit confused about how to solve that kind of questions but after few practicing, I learned how to solve those questions.

Here is an example:

This week in precalculus11 I learned about analyzing the quadratic function of the form .  Each of these words represents something on the graph.

a is the coefficient. It shows the stretch or compression of the parabola. If a > 0 parabola becomes skinnier, and if a < 1the parabola becomes wider. Also, a shows whether the parabola opens up or reflect down.

P represents horizontal translation.

q represents vertical translation.

Here is an example:
