Question

F(x) = 2x^3 + 7x^2 – 4x – 5g(2) = 3x^2 - 2-Find (f - g)(2).

Answer 1

Given:

Function is

`\begin{gathered} f(x)=2x^3+7x^2-4x-5 \\ g(x)=3x-2 \end{gathered}`

Required:

Find (f - g)(x)?

Step-by-step explanation:

We know that

`(f-g)(x)=f(x)-g(x)`

Now,

`\begin{gathered} (f-g)(x)=f(x)-g(x) \\ =2x^3+7x^2-4x-5-3x+2 \\ =2x^3+7x^2-7x-3 \end{gathered}`

Answer:

Hence, option A is correct.
