7. After taking a prescription medication, trace amounts stay in your system for an extended period of time. For example, on Wednesday, Daphne takes an allergy pill containing 128 milligrams of medicine, and takes
another on Saturday. Assume that each day Daphne's body processes half of the medicine in her system
from the day before. Determine the amount left in Daphne's system on the next Wednesday, and on what
day the amount of medication in her system will be less than 10 mg.

sine

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.
