Week 15 of pre calc 11 included a lot of fractions and aria keys. This week we learnt how to multiply and divide rational equations. When multiply and dividing there are 3 steps that I always follow.

1. Factor

2. Cross out copies

3. Rewrite the equation and simplify if possible

Lin order to find non permissible values you need to look back into the equation a and find all the factored forms with M. In this example m/=/ -3,2-2, and 0. Whenever m has acosfficient, in the example 3, then the non permissible value of m is always going to equal 0

This week we had review for our Graphing absolute values and reciprocals test, and then we did the test once Thursday. We also did our first lesson for the new unit we are starting which is, rational expressions and equations.

We already know that a rational number is a quotient of 2 integers. That means that the quotent of 2 polynomials is called a rational expression.

This example shows how the value of x changes the equation. It also shows that each value is the same for the 2 rational expressions

this week in pre cal 11, I learned how to graph absolute values. We already know that when you have an absolute value it can’t be negative, the same goes for when you are graphing it, the graph can’t go into the negative section. This means that when you graph a line you have to take the part that is INV the negative area and reflect it up so its positive.

In this example you can see that the dotted line is the part of the graph that would have continued into the negative area. Instead of it going negative the line was reflected into the positive area to make a V shape.
