(Solved): \[ f(x)=\left\{\begin{array}{ll} -\frac{1}{4} x-1 & \text { if } x1 \end{array}\right. \] Find \( f ...

\[ f(x)=\left\{\begin{array}{ll} -\frac{1}{4} x-1 & \text { if } x<-2 \\ (x+1)^{2}-3 & \text { if }-2 \leq x \leq 1 \\ 1 & \text { if } x>1 \end{array}\right. \] Find \( f(-1), f(1) \), and \( f(3) \). \[ f(-1)= \] \[ f(1)= \] \[ f(3)= \]
