Problem
Suppose that the function $f$ is defined on the interval $[-2,2)$ as follows. \[ f(x)=\left\{\begin{array}{ll} -2 & \text { if }-2 \leq x<-1 \\ -1 & \text { if }-1 \leq x<0 \\ 0 & \text { if } 0 \leq x<1 \\ 1 & \text { if } 1 \leq x<2 \end{array}\right. \] Find $f(-2), f(-0.25)$, and $f(1)$
Solution
Step 1 ：Since \(-2 \leq -2 < -1\), we have \(f(-2) = -2\).
Step 2 ：Since \(-1 \leq -0.25 < 0\), we have \(f(-0.25) = -1\).
Step 3 ：Since \(1 \leq 1 < 2\), we have \(f(1) = 1\).
Step 4 ：Therefore, \(f(-2), f(-0.25), f(1)\) are \(-2, -1, 1\) respectively.
Step 5 ：So the final answer is \(\boxed{-2, -1, 1}\).
