2. Ungkapkan \( n \) dalam sebutan \( p \) Express \( n \) in terms of \( p \). (a) \( \quad 2^{2 n}=\frac{2}{2^{n-p}} \)

\( ( 6,4 ) \quad \left\{ \begin{array} { l } { y = \frac { 3 } { 2 } x - 5 } \\ { y = x - 10 } \end{array} \right. \)

\( (4 \mathrm{p}) \) a) \( 5 x^{2}-3 x=0 \) \( (4 \mathrm{p}) \) b) \( 6 x^{2}+12 x=0 \) \( (4 \mathrm{p}) \) c) \( 8 x^{2}-24=0 \) \( (4 \mathrm{p}) \) d) \( -4 x^{2}+100=0 \) (4p) e) \( x^{2}+8 x-33=0 \) \( (4 p) \) f) \( x^{2}+9 x+20=0 \)

Diberi fungsi \( f \) ditakrifkan sebagai \( f(x)=\frac{k+x}{2+3 x}, x \neq p \), dengan keadaan \( k \) dan \( p \) ialah pemalar. Given the function \( f \) is defined by \( f(x)=\frac{k+x}{2+3 x}, x \neq p \), such that \( k \) and \( p \) are constant. Cari / Find (a) nilai bagi \( p \), the value of \( p \), (b) nilai \( k \) jika \( f(1) \) memetakan kepada diri sendiri, value of \( k \) if \( f(1) \) maps onto itself, (c) \( f^{-1}(x) \), dan seterusnya cari julat \( f^{-1}(x) \) untuk domain \( 1 \leq x \leq 3 \). \( \quad f^{-1}(x) \), and hence find the range of \( f^{-1}(x) \) for the domain \( 1 \leq x \leq 3 \).
