Even: the equation to find out if a function is even is f(-x)=f(x). this means that the function will be symmetrical to the y-axis. in other words, when the function is graphed, quadrant 1 and quadrant 2 will be a reflection of each other. so an even function looks the same as it is reflected over the y-axis.
ODD: the equation to find out if a function is odd is f(-x)=-f(x). this function will be symmetrical to the origin. in other words, this function will go through the origin and also it will remain the same as it is reflected over the x-axis and y-axis. it is taking the graph in quadrant 1 and reflecting it on both the x and y-axis.

I SOO get this =]
ReplyDeleteThis definition I gave you though. i wanted you to explain the actual equation f(x)=f(-x)...
