8. Find the Domain and Range of the function \( \begin{array}{l}\text { (i) } f(x)=\sqrt{16-x^{2}} \quad \text { (ii) } f(x)=\frac{x-1}{3 x^{2}-2 x-1} \text { (Domain only) } \\ \text { (iii) } f(x)=\frac{1}{x}-\frac{3}{x-2} \text { (Domain only) } \\ \text { 9. Consider the functions } f(x)=\left\{\begin{array}{l}x^{2}+2, x \leq 1 \\ 2 x^{2}-1, x>1\end{array} \text {, evaluate }\right. \\ \begin{array}{ll}\text { (i) } \quad f(-2) \quad \text { (ii) } f(1) \quad \text { (iii) } f(2)\end{array} \\ \text { 10. The operation * on the set } R \text { of real numbers is defined by } \\ \begin{array}{ll}\text { a. is * a binary operation on } \mathrm{R}\end{array} \\ \text { b. Is * associative } \\ \text { c. Evaluate }-2 *(-1) * 1\end{array} \)
