**MathMate**, Friday, September 16, 2011 at 4:31pmThere are three segments of functions, and two possibly discontinuous points, at x=2 and x=3.

Equate the adjacent segments to find the value of a and b that make the segments have the same values at x=2 and x=3.

Finally, check that the limits approaching from each side (2- and 2+, 3- and 3+) of the combined function are identical. They should be if the function is continuous.
