Just mutlpilpy

(4x+6) (2x^2) = 8x^3+12x^2

A is answer

Liana Stokes · Answer 2

To answer the this item, simply multiply the given functions,

(f·g) (x) = f (x) x g (x)

Plugging in the expression,

(f·g) (x) = (4x + 6) (2x²)

= 8x³ + 12x²

Thus, the answer to this item is letter A. 8x^3 + 12x^2.
