We have the following functions:
 f (x) = 4x + 1
 g (x) = x ^ 2 - 5
 Multiplying both functions we have:
 (f * g) (x) = f (x) * g (x)
 (f * g) (x) = (4x + 1) * (x ^ 2 - 5)
 Rewriting:
 (f * g) (x) = 4x ^ 3 - 20x + x ^ 2 - 5
 (f * g) (x) = 4x ^ 3 + x ^ 2 - 20x - 5
 Answer:
 The answer for this case is given by:
 (f * g) (x) = 4x ^ 3 + x ^ 2 - 20x - 5
