Defintion of an even function:
then, by definition, as well.
Sketch a possible graph of the function on the domain
Sketch another possible graph of the function on the domain
There are many ways to connect the points, just make sure you maintain symmetry over the
Can the graph be a quadratic function? If so, write a possible equation for the function. If not, explain why not.
Can you draw a parabola through all of these points? Give it a try.
