The weight of a bacterium is defined by multiplying the functions of f(x) and g(x). Given f(x) = 3x2 + 2x and g(x) = 5x. Which of the following represents the weight of the bacterium?3x2 + 7x15x3 + 10x23x2 – 3x15x2 + 10x

Respuesta :

The Solution:

Given:

[tex]\begin{gathered} f\mleft(x\mright)=3x^2+2x \\ \\ g\mleft(x\mright)=5x \end{gathered}[/tex]

Required:

Find the weight of the bacterium if the weight is the product of f(x) and g(x).

[tex]Weight=f(x)\times g(x)[/tex][tex]=(3x^2+2x)(5x)=15x^3+10x^2[/tex]

Answer: [option B]

[tex]15x^3+10x^2[/tex]
