What is a hole in a rational function graph?

Back

A hole in a rational function graph occurs at a value of x where both the numerator and denominator of the function equal zero, indicating that the function is undefined at that point.

How do you find the vertical asymptote of a rational function?

Back

The vertical asymptote of a rational function occurs at the values of x that make the denominator equal to zero, provided that these values do not also make the numerator zero.

What is a horizontal asymptote?

Back

A horizontal asymptote is a horizontal line that the graph of a function approaches as x approaches infinity or negative infinity. It indicates the behavior of the function at extreme values.

What is the significance of the leading coefficient in a rational function?

Back

The leading coefficient of the polynomial in the numerator or denominator affects the end behavior of the rational function, particularly in determining the horizontal asymptote.

What does it mean if a rational function has a hole at x = -3?

Back

If a rational function has a hole at x = -3, it means that the function is undefined at this point, and the graph will not include the point ( -3, f(-3) ).

How can you identify a hole in a rational function from its equation?

Back

To identify a hole in a rational function, factor both the numerator and denominator. If a common factor exists, the x-value that makes this factor zero indicates the location of the hole.

What is the difference between a hole and a vertical asymptote?

Back

A hole indicates a point where the function is undefined due to a common factor in the numerator and denominator, while a vertical asymptote indicates a value where the function approaches infinity.
