Which of the following equations demonstrate that the set of polynomials is not closed under the certain operations?
A. Addition: (3 x4 + x°) + (-2x4 + x) = x4 + 2x
B. Multiplication: (x2 + 2x)(x + 1) = x + 3x2 + 2x
C. Multiplication: (3x4 + x®)(-2x4 + x) = -6x8 + x + x
D. Division: (2x2 + 2x) = (x + 1) = x + 1

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

find the vertical and horizontal asymptotes of the function f x = 5 x − 1 . to find the vertical asymptote, equate the denominator to zero and solve for . since the degree of the polynomial in the numerator is less than that of the denominator, the horizontal asymptote is .
