# Week 11- Graphing Inequalities

This week, I have learned how to graph inequalities. It is very similar to graph linear graph; however, the difference is that you color.   Let’s see this example. It has the same line as linear graphing, however, we can see that there is a shaded area. It is shaded because it proves the equation that all of the shaded part is correct. The equation is : y<2x-8 We can…

# Week 10- Math mid term

This week, since there is a mid term, we had time to review our preview units. There was several things that I have forgotten from previous units. As a result, I will now explain the things that I have forgot. What does D and R stand for for Arithmetic and Geometric Sequence. D is for the difference between 2 numbers and R is the ratio between 2 numbers. How to…

# Week 9- Finding the x intercept (Zeros, Roots)

This week, I have learned how to find the x intercept from a quadratic formula. At the beginning, I was very surprised since the step it took was very simple and understandable. From y= to y= (x+2)(x+6), this was using factoring!!! Since to find x intercept needed factoring, it was very easy. Let’s begin. As I mentioned before, it is factoring. The equation, y=a(x-x1)(x-x2), x1 is your first x intercept…

# Week- 8 Finding the vertex using y=a(x−p)2+q

This I have learned how to find the vertex using y= Finding the vertex is very important to be able to graph. The vertex tells you the y-intercept, the axis of symmetry, and the range and domain. So first, lets put some numbers instead of P and Q. y= When you have this equation, your vertex will always be your P and Q, which is very interesting to me because…

# Week 7- Using quadratic formula

This week, I have learned how to use quadratic formula and see if there is a solution to the question. The equation .  Using -b+/- If there is a negative in the root sign, then the answer will not work. Example -3+/- -3+/- -3+/- Since there is -20 in the square root, it is not possible. However, if the answer was positive, there will have a answer to the equation. By…

# Week 6 – Quadratic Formula

This week, I have learn a new method to factor. Its called quadratic formula. It’s a very easy way to factor, and find the answer very easily. The first step is find what is A, B and C. For example, A would be 1 B would be -12 C would be 36   Next step will be using the formula If you plug in and fill in A, B, C,…
