Question 1125128
.


            I came to fix the errors in the post of the other tutor.



You may go in &nbsp;<U>any</U> &nbsp;of two ways.



<U>The first way</U>.


<pre>
First evaluate f(2),   where f(x) = {{{(1/2)*x+1}}} :


    f(2) = {{{(1/2)*2+1}}} = 1 + 1 = 2.


And then evaluate g(f(2)) = g(2) = {{{sqrt(2)}}}.


It is your <U>ANSWER</U>.
</pre>


<U>The second way</U>.


<pre>
Start developing the general formula for  gof(x) :


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


and then substitute x= 2 into this formula


    gof(2) = {{{sqrt((2+2)/2)}}} = {{{sqrt(4/2)}}} = {{{sqrt(2)}}}.
</pre>

By doing any way, &nbsp;you get the same &nbsp;<U>ANSWER</U> :  &nbsp;&nbsp;gof(2) = {{{sqrt(2)}}}.
