+14 Let \(f(x) = \left\{ \begin{array}{cl} -x + 3 & \text{if } x \le 0, \\ 2x - 5 & \text{if } x > 0. \end{array} \right.\)
How many solutions does the equation f(f(x) have?
Graphing, the equation f(f(x)) = 4 only has the solution x = 2. So the answer is 1 solution.
+14 I'm sorry i mistiped I meant to say: How many solutions does the equation f(f(x))=6 have???
