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
