4-3

This week in school we learned chapter 4 section 3. In 4-3 we are learned about symmetry and how to plug it in on a graph. I can have example in this sections cause there is no way for me to make a graph and stuff. I will explain how to do the problems in section 4-3.

x axis: plug in (-y), simplify( solve for y), if the equation are = then it has symmetry a/b x.
If it gives you a graph and tells you to sketch -f(x), you take the graph and draw everything on the x axis on the opposite side.


y axis: plug in (-x),simplify (solve for x), If equations are equal then it has symmetry on the y axis.
If it tells you to sketch f(-x) then you take everything on one side of the y axis and draw it to the other.
|f(x)|, flip above axis
1. plug in (-x) & (-y)
2. simplify
If it tells you to sketch |f(x)| then everything on the lower half of the axis, you draw onto the top half.

y=x is also a inverse.

Ms.Robinson this is all i can explain lmao this section is soo confusing that is why i did it to understand it more.
