Answer:
4
Step-by-step explanation:
To solve this problem let us first find
, or find <u>the function of f(x) in terms of g(x)</u>. All we have to do is replace <em>x</em> with g(x) in the function f(x):

We have to find the the degree of
, which is the largest exponent on one of the polynomial's terms. Notice that
has the greatest exponent of 4.
<u>Therefore, the degree of (fog)(x) is 4.</u>
