Question 1125128

{{{f(x)= (1/2)x+1}}}, 
{{{g(x)=sqrt(x)}}} ,


{{{h(x)=g(f(x))}}}

{{{h(x)=g((1/2)x+1)=sqrt((1/2)x+1)}}}

{{{h(x)=sqrt(x/2+1)}}}

{{{h(x)=sqrt((x+1)/2)}}}

{{{h(x)=sqrt(x+1)/sqrt(2)}}}


if {{{x=2}}}

{{{h(2)=sqrt(2+1)/sqrt(2)}}}

{{{h(2)=sqrt(3)/sqrt(2)}}}

{{{h(2)=sqrt(6)/2}}}

{{{h(2)}}} »{{{1.23}}}
