Answer 2

Answer:

A

Step-by-step explanation:

We have the two functions:

$\begin{gathered}f(x)=3x^2-2x\text{ and } g(x)=9x^2-x+7\\\end{gathered}$

And we want to find:

(f-g)(x)(f−g)(x)

This is equivalent to:

=f(x)-g(x)=f(x)−g(x)

Hence, by substitution:

$=(3x^2-2x)-(9x^2-x+7)$

Distribute:

$=(3x^2-2x)+(-9x^2+x-7)$

Rearrange:

$=(3x^2-9x^2)+(-2x+x)+(-7)$

Combine like terms:

$=-6x^2-x-7$

Hence, our answer is A.
