Polynomial and Rational Functions
How do you identify a hole in the graph of a rational function?
By identifying discontinuities in the numerator only.
By observing where the graph crosses the y-axis.
By locating where the denominator equals zero only.
By finding values that make both numerator and denominator equal zero.
A rational function has a removable discontinuity; if one occurrence each of its factors in both its numerator and denominator are removed, what remains are monic linear factors—what was one possible initial expression for this rational fun...

What happens to a rational function's vertical asymptote(s) if you multiply every term by -1?
Incorrect answer 2.
Incorrect answer 3.
The locations of vertical asymptotes remain unchanged.
Incorrect answer 1.
What is the simplified form of the rational expression ?
Cannot be simplified
What characteristic in the graph of the rational function defined by indicates there is a hole rather than an asymptote at ?
The factor (x-7) causes undefined behavior at x=-5.
The factor (x+5) cancels out.
The numerator has higher degree than the denominator.
There is a vertical asymptote at x=-5.
What horizontal asymptote, if any, does
f(x) approaches 14.
There is no horizontal asymptote.
f(x) approaches -7.
f(x) approaches 8.
In what way would replacing 'x' with '-x' in both parts of have an effect on its symmetry properties?
Replacing operation causes inversion about origin thereby altering initial condition respective towards symmetrical characteristics possessed through afore mentioned adjustments take place.
Symmetry around origin gets induced irrespective whether such property existed prior manipulation done unto .
There won't be any change regarding symmetry aspects related directly with modification imposed upon .
The function becomes symmetric about y-axis if originally it was asymmetric, otherwise, symmetry is preserved.

Which feature does NOT represent a characteristic of rational functions?
An absolute maximum value on its entire domain.
Horizontal or slant asymptotes depending on degrees of polynomials in numerator and denominator.
Asymptotes along certain lines due to division by zero issues.
Discontinuities or "holes" when common factors are canceled out.
