The relationship between the weight of a package, in ounces, and the cost to mail the package can be represented by a linear function. It costs $5.90 to mail a 16-ounce package.
It costs $6.80 to mail a 22-ounce package.
Which statement is the best interpretation of the slope of the graph of this function?

A
The minimum cost to mail a package is $3.50.

B
Each additional ounce of weight costs $0.31.

C
The minimum cost to mail a package is $0.15.

D
Each additional ounce of weight costs $0.15.

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.
