Desmond George · Answer 1

21x2 + 32x + 12; all real numbers is the answer

Salvador Hartman · Answer 2

The value of f·g is the product of f (x) and g (x). This is shown below,

f·g = (3x + 2) (7x + 6)

f·g = 21x² + 32x + 12

The domain of the function is the value of x that would make the function reasonable. The domain is all real numbers.
