Rational Function
An expression formed by dividing one polynomial by another, often resulting in asymptotes and possible holes in its graph.
Transformation
A change applied to a graph, such as shifting, reflecting, or stretching, altering its position or orientation.
Reflection
A flip of a graph over a specific axis, caused by a negative sign inside or outside the function.
Horizontal Shift
A movement of a graph left or right, determined by the value subtracted or added to the input variable.
Vertical Shift
A movement of a graph up or down, determined by a constant added or subtracted outside the function.
Vertical Asymptote
A vertical dashed line on a graph where the function approaches infinity, found by setting the denominator to zero.
Horizontal Asymptote
A horizontal dashed line indicating the value a function approaches as x becomes very large or small.
Domain
The set of all possible input values for which a function is defined, often excluding values causing division by zero.
Range
The set of all possible output values a function can produce, often split by horizontal asymptotes.
Set Notation
A mathematical way to describe collections of numbers, often using unions and parentheses to indicate intervals.
Hole
A point where a function is undefined due to a common factor in the numerator and denominator, resulting in a gap in the graph.
X-Intercept
A point where the graph crosses the x-axis, found by setting the numerator equal to zero.
Y-Intercept
A point where the graph crosses the y-axis, found by evaluating the function at zero.
Multiplicity
The number of times a factor appears in a polynomial, affecting whether a graph crosses or touches the axis at an intercept.
Interval
A section of the x-axis between known components like asymptotes and intercepts, used to analyze function behavior.
