Front

How do you determine the vertical asymptotes of a rational function?

Back

Vertical asymptotes occur at values of x that make the denominator zero, provided the numerator is not also zero at those points.

What is the difference between a function's domain and range?

Back

The domain is the set of all possible input values (x), while the range is the set of all possible output values (y).
