Flips, and Symmetry (Even, Odd)

function=vertical line test

inverse function= horizontal line test.

Now this is where it gets difficult, i am going to take some of the screenshots from the lesson today just as a reminder for the next test and so i can view them at home at a later time. This is just basic algebra, but in the end we have to apply it to some set rules that we learned today (ref to screen shots), in all honesty i haven't really caught on to any of this stuff last semester, and it is still confusing at this point. I think the only way to do well on this part of the unit is to memorize the rules and keep going over them even after the class is over. Here is what i got out of today's class:

. -f(x) is different from f(-x)
. The difference is how it is reflected (over x axis and y axis respectively)
. a inverse function is reflected over the line y=x
. EVEN function have symmetry over the y axis (flip symmetry)
. ODD functions have symmetry about the orgin (rotational symmetry)

I still am not to sure how to do the algebra parts and the comparing but i shall research that tonight and refer back to the notes tomorrow!
