I'm fed up with this question from my book. I've calculated the constants to this equation but got stuck at the asymptotes and local extreme values calculations which I need to plot the graph, perhaps anyone could help me out or guide me towards the solution of calculating the asymptotes/local extreme values and then to plot the graph.


Equation:


Define the constants A,B,C so that a function which is defined by

f(x) =
(1) (6/pi) arctan(2-(x+2)²) when x < -1
(2) x + c* |x| - 1 when -1 ≥ x ≥ 1
(3) (1/Ax+B) + 4 when x > 1 och Ax + B ≠ 0


is continuous at x = -1 and differentiable in x = 1


_______________


I calculated the constants, A,B,C to:


A = -18


B = 16


C = 7/2


Any help is appreciated,


Thanks, Michael.

Are you sure you have posted the domains correctly?

Please review your post - very carefully - and make necessary corrections. We do not want to waste time and effort on the wrong problem.

Use a graphing calculator and estimate the answers - then confirm those analytically.
