Ok i can help you solve this problem do you know the formula for quadratic equations
If you make yourself a monthly expense chart:
Months
<u> 1 2 3 4 5 6 7 8 9 10</u>
Opt 1 -80 -30 -30 -30 -30 -30 -30 -30 -30 -30
Opt 2 -40 -40 -40 -40 -40 -40 -40 -40 -40 -40
By month 5 the total amount spent for Opt 1 is $200 and Opt 2 is $200
For part two add up the values for each all the way up to month 9.
Option 1: 80 + 30(8) = 80 + 240 = 320 spent
Option 2: 40(9) = 360 spent
So option 1 is cheaper by month 9
3(5+7) is the problem you are looking at. To figure it out, you can use properties. On the right side of the equals sign, it shows a property you can use to do the problem. In this case, they are distributing.
Answer:
A shows an original investment of $200
Step-by-step explanation:
If you plug in x=0, you will get the value of the original investment
When you plug x=0 into A you get

This simplifies to

And finally to

The figure attached shows the graph of the function with the two asympotes.
The formulae of those asympotes are:
y = 3, and x = 2.This is how you work to find them.
1) The function will have
vertical asympotes where the limit grows indefinetly (approach +/- ∞).
2) That happens for
x = 2, where
the function is not defined but it grows indefinetly toward infinity (if you come from the right side) or toward negative infinity (if you come from the left side). So, the vertical asymptote is the line x = 2.
3) The function will have a
horizontal asymptote if the function tends to a constant value as x approaches infinity or negative infinity.
4) In this case, you find that
the limit of the function when x appraches - ∞ or +∞ is 3. That results in
one horizontal asymptote which is y = 3.
