6. Given: f(x) = -x+4x+12 x-3 (a) 2 points] Write f(x) in prime factored form in the numerator and denominator. (b) points] What are the y-intercept and x-intercept(s)? int: =(0,-4). (c) 3 points] Write the equations of all asymptotes (vertical/horizontal/oblique). (d) [6 points] Sketch the graph of f(x) including all intercepts and asymptotes as dotted lines. If you use test points, label them on the graph. 10 9 8 7 -8 J 6 3 2 5 6 7 8 9 10 -8 9 10 [1 point] Solve f(x) 0 using the graph. Write your answer in interval notation.
