The function mustbe cuen [ therefore e^{r} f(-x)=f(x) ] ( f(x)=frac{a^{x}-1}{x^{m}left(a^{x}+1right)} ) ( f(-x)=frac{frac{1}{a^{5 x}}-1}{(-x)^{n}left(frac{1}{a^{x}}+1right)}=frac{1-a^{x}}{(-x)^{n}left(1+a^{x}right)} ) ( 0^{circ} cdot(-x)^{n}=-x^{n} quad x^{n} ) should be odd function : " n should be odd Anis (D) ( n=-frac{1}{3} )
