+193 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 $f(f(x)) = 4$ have?

Let
\(f(x) = \left\{ \begin{array}{cl} -x + 3 & \text{if } x \le 0, \\ 2x - 5 & \text{if } x > 0. \end{array} \right. \)
Hallo clairepow!
\(f(x)=-x+3\\ Domain =\mathbb R|-∞< x \leq 0\\ Range=\mathbb R|3 \le y<∞\)
\(f(x)=2x+5\\ Domain =\mathbb R|0< x <∞\\ Range=\mathbb R|-5< y<∞\)
