Given the following functions f(x) and g(x), solve (f ⋅ g)(3) and select the correct answer below: f(x) = 4x^2 + 12 g(x) = x − 1 47 −47 96 −96

For this case we have the following functions:
 f (x) = 4x ^ 2 + 12
 g (x) = x - 1
 Multiplying the functions we have:
 (f ⋅ g) (x) = f (x) * g (x)
 (f ⋅ g) (x) = (4x ^ 2 + 12) * (x - 1)
 Evaluating for x = 3 we have:
 (f ⋅ g) (3) = (4 (3) ^ 2 + 12) * (3 - 1)
 (f ⋅ g) (3) = (4 (9) + 12) * (2)
 (f ⋅ g) (3) = (36 + 12) * (2)
 (f ⋅ g) (3) = (48) * (2)
 (f ⋅ g) (3) = 96
 
 (f ⋅ g) (3) = 96
