Determine if F(x) = (1/3)x-3 and g(x)= 3x+9 are inverse functions by computing their compositions.
\n" ); document.write( "-------------
\n" ); document.write( "f[g(x)]=f[3x+9]=(1/3)(3x+9)-3=x+3-3=x
\n" ); document.write( "g[f[x)]=f[(1/3)x-3]=3[(1/3)x-3]+9=x-9+9=x
\n" ); document.write( "They are inverse of one another.
