Solution:
Let the following function:
[tex]g(n)=n^2+2[/tex]
if we evaluate n=3 in the previous equation, we get:
[tex]g(3)=3^2+2[/tex]
this is equivalent to
[tex]g(3)=\text{ (3x3) +2 = 9+2 = 11}[/tex]
that is:
[tex]g(3)=11[/tex]
so that, we can conclude that the correct answer is:
[tex]g(3)=11[/tex]
