1. If \( f(x)=\left\{\begin{array}{ll}-x^{2}-3 x & x \leq-1 \\ 2 x+3 & -1<x \leq 2\end{array}\right. \), computer the folls \( \begin{array}{lll}\text { (a) } f(-3)= & \text { (b) } f\left(\frac{1}{2}\right)=2\end{array} \) (e) What is the domain of \( f \) ?

3. \( \frac{2}{6}=\frac{\square}{12} \)

1. \( \frac{4}{5}=\frac{\square}{10} \)

Select the number that is 5 less than a square number. \[ \begin{array}{cccc}30 & 46 & 59 & 86 \\ \text { A } & \text { B } & \text { C } & \text { D }\end{array} \]
