What is the ratio of Erin's tennis trophies to soccer trophies?
Choose 1
3:7
B
4:7
7:4
3:12
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! : )

120 seems like the most sensible answer.
step-by-step explanation:
if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?
