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
option 1
