The weight of a bacterium is defined by multiplying the functions of f(x) and g(x). Given f(x) = 2x² + 6x and g(x) = 12x. Which of the following represents the weight of the bacterium?

ANSWER:
4th option: 24x³ + 72x²
STEP-BY-STEP EXPLANATION:
We have the following functions:
[tex]\begin{gathered} f\mleft(x\mright)=2x²+6x \\ \\ g\mleft(x\mright)=12x \end{gathered}[/tex]We multiply them and obtain the following:
[tex]\begin{gathered} f(x)\cdot g(x)=\left(2x^2+6x\right)\cdot12x \\ \\ f(x)\cdot g(x)=24x^3+72x^2 \end{gathered}[/tex]Therefore, the correct answer is 4th option: 24x³ + 72x²
