F(x) is a polynomial with real coefficients. Hence for any real numbers x, ...
• f(x) is a real-valued function
• f(x) is continuous on any closed interval of real numbers, such as [4, 6]
• f(x) is differentiable on any open interval of real numbers, such as (4, 6)
The conclusion is that there exists some "c" such that f'(c) = (f(6) -f(4)/(6 - 4).
The slope of interest is
m = (f(6) -f(4))/(6 -4) = (-44 -(-44))/2 = 0
The slope f'(x) is -20 +4x. It will be zero where
0 = -20 +4x
20 = 4x
5 = x
So, f'(5) = 0 = m
The point "c" of interest is
c = {5}

48 * .5 = 24
24 the amount of money discounted off the price
Therefore it would be 48 - 24 = 24, but then comes the sales tax.
Do 24 * .045 = 1.08
1.08 is the amount of tax owed on the game so you'd do
24 + 1.08 = 25.08
A) The total cost for the game is 25.08
B) Unfortunately he is short by 8 cents and won't be able to buy the video game he wants.
ANSWER=30
because if you 8.2-2.3 you get 5.9 and if you divide by 177 it is 30
hope it helps
