What is the end behavior of a polynomial function?

Back

The end behavior describes how the function behaves as x approaches ±∞.

Front

What is the difference between even and odd functions?

Back

Even functions are symmetric about the y-axis; odd functions are symmetric about the origin.

How do you find the sum of two functions?

Back

To find the sum (f + g)(x), add the outputs of f and g for the same input x.
