\begin{tabular}{l|l} Find the zeros of the polynomial function, and state the multiplicity of each. \\ \( f(x)=(x+2)^{3}(x-1) \) & The zeros are \( \square \).\end{tabular}

\( \lim _{n \rightarrow ooovvv} () \)

\( k=\frac{1}{1-c(1-t)} \left\lvert\, \begin{array}{l}k=\text { Multiplicador } . \\ c=\text { Propensión marginal } \\ t=\text { Tesa impositiva. }\end{array}\right. \)
