5. Rational Functions

Sketch the graph of the function $f\(\left\)(x\(\right\))=\(\frac{1}{x^2}\)$. Identify the asymptotes on the graph.

Based only on the vertical asymptotes, which of the following graphs could be the graph of the given function? $f\(\left\)(x\(\right\))=\(\frac{x^2-4x}{x^2-x-12}\)$

Find all vertical asymptotes and holes of each function.

$f\(\left\)(x\(\right\))=\(\frac{-5x}{\left(2x-3\right)^2}\)$

Find all vertical asymptotes and holes of each function.

$f\(\left\)(x\(\right\))=\(\frac{x^2-2x}{2x^3-x^2-6x}\)$

Find the domain of each rational function. g(x)=3x²/(x−5)(x+4)

Find the domain of each rational function. h(x)=(x+7)/(x²−49)

Use the graphs of the rational functions in choices A–D to answer each question.

There may be more than one correct choice. Which choices have domain (-∞, 3)U(3, ∞)?

Use the graph of the rational function in the figure shown to complete each statement in Exercises 9–14.

As $x\to 1^{-},f\left(x\right){\to }_{{}_{}}$______
