Question 114

Multiple Choice

Find f[g(x) ]f[g(x) ] and g[f(x) ]g[f(x) ] .
- f(x) =23x;g(x) =54xf(x) =\frac{2}{3 x} ; g(x) =\frac{5}{4 x}


A) f[g(x) ]=15/8x;g[f(x) ]=8/15xf[g(x) ]=15 / 8 x ; g[f(x) ]=8 / 15 x
B) f[g(x) ]=8/15x;g[f(x) ]=15/8xf[g(x) ]=8 / 15 x ; g[f(x) ]=15 / 8 x
C) f[g(x) ]=15x/8;g[f(x) ]=8x/15f[g(x) ]=15 x / 8 ; g[f(x) ]=8 x / 15
D) f[g(x) ]=8x/15;g[f(x) ]=15x/8f[g(x) ]=8 x / 15 ; g[f(x) ]=15 x / 8
