For each function
The sketch of
should be identical to the given graph .
On this graph,
Plot all negative
-values in the positive region, and plot all positive -values in the negative region.
EVEN AND ODD FUNCTIONS--INFORMALLY
A function that is symmetric with respect to the
-axis, like that in part (a) above, is called an even function. A function that is symmetric with respect to the origin, such as that in part (b), is called an odd function.
Sketch examples of even and odd functions. Include how you can test whether a function is even or odd. Then list some famous even/odd functions from your parent graphs, and the symmetries associated with even and odd functions.
Even functions are symmetrical ACROSS the
Graph (a) is even. Graph (b) is odd.
Famous even functions include:
Famous odd functions include:
