UAEA SPN\newlinePRAKTIS SUMAT\newlineKERTAS\newline11. Fungsi f f ditakrifkan oleh f(x)=2xx+4,x≠−4 f(x)=\frac{2 x}{x+4}, x \neq-4 .\newlineThe function f f is defined as f(x)=2xx+4,x≠−4 f(x)=\frac{2 x}{x+4}, x \neq-4 .\newline(a) Cari ungkapan bagi f2(x) f^{2}(x) dan f−1(x) f^{-1}(x) . Find the expressions of f2(x) f^{2}(x) and f−1(x) f^{-1}(x) . SP 11.22.22 SP 11.33.33 [44 markah / 44 marks]\newline(b) Seterusnya, cari nilai x x jika f2(x)=f−1(x) f^{2}(x)=f^{-1}(x) dengan keadaan f(x)=2xx+4,x≠−4 f(x)=\frac{2 x}{x+4}, x \neq-4 00. SP 11.22.55\newline- Hence, find the value of x x if f2(x)=f−1(x) f^{2}(x)=f^{-1}(x) such that f(x)=2xx+4,x≠−4 f(x)=\frac{2 x}{x+4}, x \neq-4 00. [33 markah / 33 marks]\newlineJawapan / Answer:\newline(a)\newline22. Fungsi f(x)=2xx+4,x≠−4 f(x)=\frac{2 x}{x+4}, x \neq-4 44 gubah tentuk\newlineFunctior f(x)=2xx+4,x≠−4 f(x)=\frac{2 x}{x+4}, x \neq-4 55 defined of f(x)=2xx+4,x≠−4 f(x)=\frac{2 x}{x+4}, x \neq-4 66.\newlineJawap\newline33.
