The politician's popularity rating was 50%. Then he began to lose popularity at a rate of 10% per week. If R = current rating and W = weeks, which is the correct equation? A. R = 10W-50B
B. R= -50W + 10
C. R= 50W - 10
D. R=-10W + 50
E. R = -10W - 50​

answer: procent 54 wynosi 33,33%

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.

you 're wlecome! : )
