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 \( f \) ?

10. Jika fungsi kuadrat \( y=-x^{2}-6 x-8 \) mempunyal sumbu simetri \( x=-3 \) maka nilai maksimum fungsi tersebut adalah ... \( \begin{array}{ll}\text { A. }-2 & \text { D. } 1 \\ \text { B. }-1 & \text { E. } 8 \\ \text { C. } 0 & \end{array} \)

Use a calculator to approximate each to the nearest thousandth. \( \log _{5} 6 \)

26. Nilai dari \( -1^{2}+(-4)^{0}+9^{\frac{1}{2}}-\left(\frac{1}{2}\right)^{-2} \) adalah ...

Use a calculator to approximate each to the nearest thousandth. \( \log _{6} 4.1 \)

5. \( \frac{-35-15 i}{5 i} \)
