Answer:
Y = 7
Step-by-step explanation:
You would add 4 to both sides to cancel out the -4. That leaves y by itself equaling 7.
We can split it up into

I see you were supposed to use synthetic division
not sure what the 'related function is'
but as |x| approaches positivie infinity, y approaches positive infinity
as |x| approaches negative infinity, y approaches positive infinity
for the original function
as x approaches positivie infinity

approaches positive infinity
as x approaches negative infinity

approaches positive infinity
this is due to the x^2 term making it positive
It depends on what kind of pencil it is.
The answer for this would be 3y
