Kallie has $45.50 saved towards a new bike. If the bike costs $184.76 Including tax, how much does she have to save each week to be able to buy it in 6 weeks? Kallie starts her solution but does not finish.
184 76-45 50 - 139.26
Which equation would be the second step of this solution?
O x-139 26-6
X- 6x139.26
X6-139.6
X-6x45 50

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! : )
