f(x) = 4x3 + 6x2 – 3x – 4g(x) = 4x – 3Find (f - 9)(x).A. (f - g)(x) = 4x3 + 6x2 + x - 1B. (f - g)(x) = 4.23 + 6x2 – 7x – 7c. (f - g)(x) = 4x3 + 6x2 + x - 7O D. (f - g)(x) = 4x3 + 6x2 – 7x - 1SUBMIT

Respuesta :

[tex]\begin{gathered} \\ F(x)=4x^3+6x^2-3x-4\text{ } \\ g(x)\text{ = 4x - 3} \end{gathered}[/tex]

Step1:

You are to subtract g(x) from f(x)

Step2:

Simplify and collect like terms

therefore,

[tex]\begin{gathered} \\ (f-g)x=4x^3+6x^2\text{ - 3x - 4 - (4x - 3)} \\ =4x^3+6x^2\text{ - 3x - 4 - 4x + 3} \\ \text{Next add like terms} \\ =4x^3+6x^2\text{ -7x - 1} \end{gathered}[/tex]

Option D is the correct answer
