Question 1178520


{{{f(x) = sqrt(x)}}} 
{{{ g(x) = 4x + 8}}}

{{{f}}}∘{{{g}}}={{{f(g(x))}}}

{{{f}}}∘{{{g}}}={{{f(4x + 8)}}}

{{{f}}}∘{{{g}}}={{{sqrt(4x + 8)}}}

domain:

 

{{{4x + 8=0}}}

{{{4x =-8}}}

{{{x =-2}}}

{ {{{x}}} element {{{R}}} : {{{x>=-2}}} } (assuming a function from reals to reals)
