Even and Odd funcys (functions)

The first image there shows an even funtion and the second one shows an odd function.

EVEN function:

For any function of f(x),when you alter the input (x), the graph of the function changes. In this case the image of the graph is mirrored when the input is made negative. Therefore, if a graph that is symmetrical about the y-axis is transformed into f(-x), it will be exactly the same as the orginal function.

ODD function:

In odd functions the oppisite is shown. Symmetry is one of inversion at the origin in an odd function. Any point in the top right quadrant leads onto one at the bottom, thus proving an odd function f(-x) = -f(x). and commonly uses odd powers.

About Me.
Hey there people, my name is Charlie and I'm 17 years old. I'm a boring Dude who doesn't talk that much. I like reading books/mangas (that seem to be interesting), I like listening to music (always listened to hip-hop and rap but now i only listen to rock, metal, punk, and emo-screamo), I like watching history, comedy, and horror movies, and i really love drawing (but I only draw when I'm bored).
Back then, I used to be an energetic person, I loved having conversations with my friends, workin out was one of my hobbies, i used to laugh most of the time, i was friendly, i used to help out my friends who needed me....friends who needed a friend to talk with, friends who needed advice on how to resolve their problems with their girlfriends, friends who needed tips on how to make a girl fall for them (i used to tell them to be gentlemen, not to talk about how great they are, and i told them to be honest to the girl they like and to be honest to themselves),---and i used to be a happy person/student (used to be the class clown). I used to be all that back then, but now i've changed a lot......i'm lazy, boring, i won't even talk to anybody, i won't even say hi/hello to anybody when i see them (i just look at them and leave without saying anything), when i'm walking, my friends catch up and try to walk with me but then when i feel bored of them, i just walk faster and leave them behind, i used to talk about my problems to my friends but now i just keep them inside and wait til i burst out in fury just to solve them. And also now, i don't listen to what people have to say about me, about my dress (i used to wear huge shirts...not because i was actually huge..., but now i just wear medium shirts...the ones that fits me well, also now i wear black everyday.),---and what they have to say about my hair (i used to be bald every mester but now i love having long hair and hoping for it to grow more longer so i can start putting style to it).
Btw i love being alone, doing things alone, and walking alone (like the song:I walk Alone by Saliva and/or Greenday) and also everyday i show my face to the world...i only show serious, sad, and empty face....Idk why but I'm used to it.

Well that's all about me for now, if u want more...just add me/suscribe, ask me, w/e....i won't answer you. (LOL joke)
