A. $f(x)=\frac{2}{3}xf(x)=\backslash frac\{2\}\{3\}\; x$

B. $f(x)=-\frac{2}{3}{x}^2-\frac{8}{3}xf(x)=-\backslash frac\{2\}\{3\}\; x^\{2\}-\backslash frac\{8\}\{3\}\; x$

C. $f(x)=2^{1+\frac{x}{3}}-2f(x)=2^\{1+\backslash frac\{x\}\{3\}\}-2$

D. $f(x)={\log }_2(x+1)f(x)=\backslash log\; \_\{2\}(x+1)$
