c. EVEN AND ODD FUNCTIONS—INFORMALLY
A function that is symmetric with respect to the y-axis, like the one in part (a) above, is called an even function. A function that is symmetric with respect to the origin, like the one 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 that you have studied in a previous course, 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:
