Question 306

Multiple Choice

Find f[g(x) ]f[g(x) ] and g[f(x) ]g[f(x) ] .
- f(x) =7/(x) 4;g(x) =2x3f(x) =7 /(x) ^{4} ; g(x) =2 x^{3}


A) f[g(x) ]=7/16x12\mathrm{f}[\mathrm{g}(\mathrm{x}) ]=7 / 16 \mathrm{x} 12
g[f(x) ]=686/(x) 12g[f(x) ]=686 /(x) ^{12}
B) f[g(x) ]=7x12/16f[g(x) ]=7 x^{12} / 16
g[f(x) ]=x12/686\mathrm{g}[\mathrm{f}(\mathrm{x}) ]=\mathrm{x}^{12 / 686}
C) f[g(x) ]=7x12/686f[g(x) ]=7 x^{12} / 686
g[f(x) ]=x12/16\mathrm{g}[\mathrm{f}(\mathrm{x}) ]=\mathrm{x}^{12 / 16}
D) f[g(x) ]=686/7x12f[g(x) ]=686 / 7 x^{12}
g[f(x) ]=16/(x) 12\mathrm{g}[\mathrm{f}(\mathrm{x}) ]=16 /(\mathrm{x}) ^{12}
