Unformatted text preview: nd as with the previous example this is also an x-intercept. In this case the coefficient of the 5th degree term is negative and so since the degree is odd the graph will increase without bound on the left side and decrease without bound on the right side. Here are some function evaluations. P ( -3) = 135 P ( -1) = -3 P (1) = 3 P ( 3) = -135 Alright, this graph will start out much as the previous graph did. At the left end the graph will be decreasing as we move to the right and will decrease through the first x-intercept at x = -2 since know that this x-intercept crosses the x-axis. Now at some point we’ll get a turning point so the graph can get back up to the next x-intercept at © 2007 Paul Dawkins 261 http://tutorial.math.lamar.edu/terms.aspx College Algebra x = 0 and the graph will continue to increase through this point since it also crosses the x-axis. Note as well that the graph should be flat at this point as well since the multiplicity is greater than one. Finally, the graph will reach anoth...
