The polynomial -3 x 2 +400 X represents the budget surplus of the town of alphaville for the year 2010. Alphaville surplus in 2011 can be modeled by -15 x 2 + 200 x. If x represents the yearly tax revenue in thousands, enter a polynomial for how much alphaville budget surplus increase from 2010 to 2011. If alphaville took in $450,000 in tax revenue in 2011, what was the budget surplus this year?

Question 1: Budget Surplus Increase =

Question 2: Budget surplus in 2011 = $

Step-by-step explanation:

Question 1

Budget surplus in 2010 =

Budget surplus in 2011 =

Increase in buget surplus = Budget surplus in 2011 - Budget surplus in 2010

Question 2

2011 yearly tax revenue, x = $450,000

Budget surplus in 2011 =

Budget surplus in 2011 ≅ $

step-by-step explanation:

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
