Given a list of 4096 sorted values, about how many comparisons
can you expect to be performed to look for a value that's not in
the list using the

Calculate the Y values corresponding to the X values given
below. Find the critical values for X for the given polynomial by
finding the X values among those given where the first derivative,
dy/dx = 0 and/or X values where the second derivative, d¬2y/dx2 =
0. Be sure to indicate the sign (+ or -) of dy/dx and of d2y/dx2
tabled values. Using the first and second derivative tests with the
information you have calculated, determine which X value(s)
represent...
Calculate the Y values corresponding to the X values given
below. Find the critical values for X for the given polynomial by
finding the X values among those given where the first derivative,
dy/dx = 0 and/or X values where the second derivative,
d2y/dx2 = 0. Be sure to
find the sign (+ or -) of dy/dx and of
d2y/dx2 at all X values. Reference Lesson 13
and the text Appendix A (pp 694 – 698), as needed. Using the...
