Question

Consider the function that satisfies the following:

  • the only intercept points of the graph of are (−4, 0), (0, 0), and (5, 0)
  • lim x->2^+ f(x) = -∞, lim x->2^- f(x) = +∞, lim x-> -∞ f(x) = 2, and lim x-> +∞ f(x) = 2
  • f(-2) = -2
  • is continuous everywhere (except at = 2)
  • the table of signs is also given (photo attached)

Question:

  1. Sketch the graph of f with emphasis on the concavity. Label all the important points (intercept points, asymptote with their equations, inflection points, and relative extremum points)
