Removable Discontinuity Vocabulary

What is a removable discontinuity?

• A point on the graph where the slope is zero.

• A point on the graph of a rational function where the function is undefined, but the discontinuity can be 'removed' by simplifying the function.

• A point where the graph intersects the x-axis.

• A point where the function's value approaches infinity as x approaches a specific value.

Vertical Asymptote

• A vertical line that the graph crosses when the denominator equals zero.

• A point on the graph where the graph intersects the x-axis.

• A vertical line that the graph of the function approaches but never touches, caused by a non-cancelled factor in the denominator.

• A point where the numerator equals zero.

Zero of a Function

• A vertical asymptote where the graph crosses the x-axis.

• A point where the function approaches infinity.

• The x-value where the numerator of the rational function equals zero, making the function’s value zero.

• A point on the graph where the denominator equals zero.

Factorable Form

• The function is written as a sum of fractions.

• The function is written as a product of terms that cancel out.
