Answer:
Step-by-step explanation:
It never occurred to me that the closed circle meant multiplication. The most common symbol for multiplication here is *. If that is what is meant (closed circle = multiplication) then my answer is wrong.
f(x) = 3x + 1
g(x) = x^2 - 6
f(x)(g(x)) = (3x + 1)(x^2 - 6)
f(x)(g(x)) = 3x^3 - 18x + x^2 + 6 or more properly
f(x)(g(x)) = 3x^3 + x^2 - 18x - 6
