What is a function?

A function is written n the form of f(x) equals to a function. f(x) is equivalent to y. In order to test rather the equation is a function, we can use the vertical line test.  It is only a function when the one x glue has one y value. X-intercepts are also called solutions and zeros. In order to find the x-intercepts, we set the f(x) to 0 and solve for x.  When we can't factor a quadratic equation, we use the quadratic formula. Functions and graphs are not so hard, I like them. 

What I learned this week.

This week we reviewed real numbers, inequalities, absolute values, and equations of circles. In addition to inequalities, we learned how to write set notations, and how to use sign chart method to solve inequality equations with x^2. We learned how to solve inequalities with absolute values. We also reviwed the distance formula and midpoint formula. We reviewed intercepts and we learned the formula for semicircles. We reviewed how to rewrite the equation of circle if it is not written in the standard format. We also reviwed how to graph a circle.  

All about me

My name is blair.. :) I like music, I play guitar, piano, and I write songs.  I like to read the lyrics when I listen to music. My favorite subjects in school are English, music, math and science.  I do not like history.  I like to travel, I prefer tropical areas but not the near beach. I like humid air but not salty humid air.  I love animals, and I wish to have a cat named Peanutbutter in the future. I had a beta fish named Peanut, I loved it a lot.  He died last year and I was really sad. :(    I don't do sports, I am a more musical person.  I came to America 3 years ago, I am enjoying the experience so far. I wan to study music in college. My dream schools are USC Thornton College of music, and Berklee college of music.   My goal this year is to get solid grades and aim for 800 on SAT in Math section.  I guess that's all about me, this thing is so long ...... :D
