Given the functions f(x) = 7x + 13 and g(x) = x + 2, which of the following functions represents f[g(x)] correctly?
f[g(x)] = 7x + 15
f[g(x)] = 7x + 27
f[g(x)] = 7x2 + 15
f[g(x)] = 7x2 + 27

Best ResponseYou've already chosen the best response.0\[given f(x)=7x+13 , g(x)= x+2\] now \[f[g(x)]=7(x+2)+13\] \[f[g(x)]=7x+14+13\] \[\therefore f[g(x)=7x+27\]
