Problem
For the piecewise linear function, find $(a) f(-3),(b) f(-1),(c) f(0),(d) f(2)$, and $(e) f(5)$. \[ f(x)=\left\{\begin{array}{ll} 2 x & \text { if } x \leq-1 \\ x-1 & \text { if } x>-1 \end{array}\right. \] (a) $f(-3)=$
Solution
Step 1 ：We need to find the value of the function at x = -3. Since -3 is less than or equal to -1, we will use the first part of the piecewise function: \(f(x) = 2x\).
Step 2 ：x = -3
Step 3 ：f_x = -6
Step 4 ：Final Answer: \(\boxed{-6}\)
