Answer 1

Question:

Solution:

By definition of composition of functions, we have that:

$(g\circ f)(x)=\text{ g(f(x))}$

Now, according to the table, if we evaluate above in x=3, we get:

$(g\circ f)(3)=\text{ g(f(3)) = g(2)=5}$

so that, we can conclude that the correct answer is:

$(g\circ f)(3)=\text{5}$
