Question:
Solution:
By definition of composition of functions, we have that:
[tex](g\circ f)(x)=\text{ g(f(x))}[/tex]Now, according to the table, if we evaluate above in x=3, we get:
[tex](g\circ f)(3)=\text{ g(f(3)) = g(2)=5}[/tex]so that, we can conclude that the correct answer is:
[tex](g\circ f)(3)=\text{5}[/tex]
