Please show me the work and answer. Thank you.

9) Graph the rational function f(x) = x-3 x- - 9 using the seven step strategy a) Domain: b) Vertical Asymptotes: c) Holes (if any): Horizontal Asymptote: Y-Intercept f) X-Intercept(s) g) Sketch the graph of this function. Plot intercepts and holes where applicable. Draw the asymptotes as dashed lines. 10) The rational function R(x)= _ -x-1 has a slant asymptote. x-1 a) Explain how the degree of the numerator and denominator can help us determine whether a rational function will have a slant asymptote. b) Find the slant asymptote c) Find the intercepts d) Find any vertical asymptotes e) Sketch the graph of this function. Plot intercepts, additional points and holes where applicable. Draw the asymptotes as dashed lines.Section 2.7: Polynomial and Rational Inequalities 11) Use the graph the function, f(x) as shown below to solve each inequality. Write the solution to each inequality in interval notation. 3- 2. 1- - 5 -4 -3 -2 -1 2 4 /5 6 -1- -4 -5- a) f(x) >0 b) f ( x) 0 b) f ( x) 2 . Write the solution in interval notation. x-1 15) Find the domain of the function f(x) =
