Answer: $g(x)-f(x)=-2x-8$

Step-by-step explanation:

Given parent functions : $f(x)=5x-1\text{ and }g(x)=3x-9$

Then ,

$g(x)-f(x)=3x-9-(5x-1)\\\\\Rightarrow g(x)-f(x)=3x-9-5x+1\ \ \text{[Open brackets]}\\\\\Rightarrow g(x)-f(x)=3x-5x-9+1\ \ \text{[Combine like terms]}\\\\\Rightarrow g(x)-f(x)=-2x-8$

Hence, for the given parent function f(x) and g(x), $g(x)-f(x)=-2x-8$

g(x) –f(x) = 3x –9 - (<span>5x –1)
</span> g(x) –f(x) = 3x –9 - 5x + 1
g(x) –f(x) = -2x - 8
<span>
hope it helps

The correct answer is: [B]: " $\frac{(-3)(4)}{(6)}$ " .
__________________________________________________________
Consider choice [A]: $\frac{(3)(4)}{(6)}$ ;
= $\frac{12}{6}$ ;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [A]" .
__________________________________________________________
Consider choice [B]: $\frac{(-3)(4)}{(6)}$ ;
= $\frac{-12}{6}$ ;
= "-2" ; Yes!
→ Let us proceed with the final answer choice ;
__________________________________________________________
Consider choice [C]: $\frac{(-3)(-4)}{(6)}$ ;
= $\frac{12}{6}$ ;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [C]" .
__________________________________________________________
The correct answer is: [B]: " $\frac{(-3)(4)}{(6)}$ " .
