Question

f(x) = 4x3 + 5x2 – 3x - 6g(x) = 4x - 5Find (f - 3)(x).O A. (f - g)(x) = 4x3 + 5x2 – 7x – 1O B. (f - g)(x) = 4x3 + 5.02 +0 - 1O c. (f - g)(x) = 4x3 + 5x2 – 7x – 11O D. (f - g)(x) = 4x3 + 5x2 + x - 11SUBMIT

Answer 1

`\begin{gathered} f\mleft(x\mright)=4x^3+5x^2-3x-6 \\ g\mleft(x\mright)=4x-5 \\ Find\mleft(f-g\mright)\mleft(x\mright). \\ \\ (f-g)(x)=f(x)-g(x) \\ =(4x^3+5x^2-3x-6)-(4x-5) \\ =4x^3+5x^2-(3x+4x)-6+5 \\ =4x^3+5x^2-7x-1\text{ } \\ \\ \text{Thus the answer is A} \end{gathered}`
