Polynomial and Rational Functions
For a rational function like , which condition must be true for to have a removable discontinuity at some point ?
cx + d never equals zero.
ax + b has a higher degree than cx + d.
The graph has a vertical asymptote at .
cx + d equals zero at but also equals zero at same .
If two angles are complementary, and one measures 30 degrees, what is the measure of the other angle?
60 degrees
45 degrees
120 degrees
90 degrees
Compare Rational functions to distance-time graphs of two objects moving along paths. Calculate which object's path is longer over the interval [0, 5].
Both paths are equal because both objects have consistent speeds and distances covered are equal.
Interval of object with a longer path due to a greater numerator affecting altitude.
Interval of object with a shorter path since it has a larger denominator influencing the steepness of the curve.
Both objects travel at the same pace, thus the identical intervals are covered.
What is the horizontal asymptote of the rational function ?
y = 3
x = -4
y = -4
x = 3
If g(x) = , what is g(3)?
Undefined
Negative two
Zero
Eight
For which values of m would the rational function have an horizontal asymptote at y=m?
Exclusively if m is an integer.
Any real number except zero.
None; the equation always has an horizontal asymptote at y=q.
Only when m is greater than one.
What type of discontinuity is present at a point where a rational function is undefined due to division by zero?
Removable discontinuity
Jump discontinuity
Continuous
Infinite discontinuity

What describes best how to find zeros from a given rational function's equation?
Add both numerator and denominator together set equal to zero then solve for x.
Set denominator equal to zero and solve for x.
Set numerator equal to zero and solve for x.
Multiply both numerator by denominator set equal to zero then solve for X.
How would adding a term to a rational function's denominator containing an existing variable affect its horizontal asymptote?
The location of all previous horizontal asymptotes will shift up or down based on that term’s value
There may be no effect if it doesn't alter highest-degree terms' ratio between numerator and denominator
All previously existing horizontal asymptotes will disappear entirely from its graph
A new horizontal asymptote will always form at y = that term's coefficient.
What is the horizontal asymptote of the rational function ?
x = 0
y = 6
x = 6
y = 0
