Given f(x) = 6x + 2 and g(x) = x3 , what is f(x) g(x)?

f (x) * g (x) = 6x⁴ + 2x³

Explanation:
We are given that:
f (x) = 6x + 2
g (x) = x³

We want to get:
f (x) g (x) which is simply the multiplication of the two functions.

Therefore:
f (x) * g (x) = (6x+2)(x³)
f (x) * g (x) = x³(6x) + x³(2)
f (x) * g (x) = 6x⁴ + 2x³

Hope this helps :)
