# Week 15- Adding and Subtracting of Rational Expression

This week, I have learned how to add and subtract rational expression. First, as it is similar to fractions, you must make the denominator the same Second, we multiply the top number with the opposite denominator. In this picture, since it has the same denominator, you can add or subtract right away. Finally, you simplify. If you see something that are the same, you can cross them out to get…

# Week 14- Quivalent Rational Expressions

This week, I have learned how to rationalize expressions (quivalent). In the example, we have x+4 and (x-3)x(+4) We first want to divide each sides by x+4 because they are both common. As x+4 / x+4 is 1 the top is 1 and there is x-3 left. Let’s try something harder Now we have a harder example. First we want to take out commons. and 2x, x+4. When we cross…

# Week 13- Finding Asymptotes

This week, I have learned how to find the Asymptotes from a graph of linear. I was very surprised that it was very simple to find. For example on the graph above, x=0 and y=1 This is simple to find since you need to find the gaps between both of them. It is very interesting since I have never seen this kind of graph in my life.

# Week 12 – Graphing absolute value

This week, I have learned how to graph absolute values. The difference between last week and this unit, There is a lumps everywhere.   On the graph, you can see there is a lump in the middle. This is because of absolute value. when you add absolute value signs, the answer can’t be negative. As a result, there is a lump in the middle which is the new vertex. This also…
