I am reasking this question because i still don't have an answer. THank you for all the help that you have given me on my other questions.

Let g(x) be a function piecewise defined as

$$g(x) = \left\{ \begin{array}{cl} -x & x\le 0, \\ 2x-41 & x>0. \end{array} \right.$$

If a is negative, find a so that $$g(g(g(10.5)))=g(g(g(a))).$$

THank you SO MUCH IN ADVANCE. ^_^

Step through it one g at a time

g(10.5) = 2(10.5)-41 = -20

g(-20) = 20

g(20) = 2(20) - 41 = -1     for the left hand side of the equation

g  (g g a) = -1      so    2x-41 = -1      2x= 40    x = 20

g   ga = 20        so     ga =       20 = 2x-41    2x= 61  x = 30.5

g(a) = 30.5      a = -30.5
