This week in math was a bit of a struggle for me as some of the topics were difficult. But, as the week went along, and especially during the weekend, I felt that a light switch went off, and I started to understand some of the concepts in this unit. The biggest thing I got was understanding function notation and what it means/does. Function notation is, for example, f (4) = 0.  Before being able to write this, I had to put the 4 on the x-axis and the 0 on the y-axis. The next step for writing the f (4) = 0 is actually a lot simpler than you would, as you are just copying down what you just did. In other words, you are using your eyes to do the math. That is the other big thing I learned. 80% of this unit is just reading the question properly and letting your eyes do the math. In fact, like in this question, there is a lot of copying down and if you know what you are supposed to do, it is a lot easier than some people think. Another example where I let my eyes do the math was finding the domain and range to an ordered pair. To find the domain of 8,3, all you need to do is find 8 on the x-axis, then 3. Following this, you need to see what it is equal to. Lastly, it is very important to remember that the domain is x, and the range is y!
