Answer:
I believe the answer is C. hope this helps
The answer would be the top left one because when dividing, you would subtract 8 from 13. I'm pretty sure not 100% though. Sorry.
A equals 3
Equation is g(x)=3f(x)
What i did is notice the y intercept is at 3 so I plugged in x=0 into the parent equation and got f(0)=1
So to get this equation to the y=3 intercept which is the g function, you have to multiply it by 3
