Jackie wants to start a garden in her backyard to grow vegetables. She built a frame that is 8 feet by 10 feet. She figures that she will need to add in top soil to be one foot deep. She goes to the local garden store to shop for soil and sees the following options for purchasing bags of soil : Brand A: 120 Ibs for $6 and Brand B : 200 Ibs for $8 Part A: what is the unit rate that Brand A is selling for? Ibs/dollar
Part B: which brand is offering better value? ( Brand A or Brand B) ?

any options?

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.
