a rocketry club is holding a competition. There is a cloud cover at 1000 ft that extends across the sky. The rocket is launched at an initial velocity of 275 ft/sec from a height of 3 feet. The function models of height of the rocket in feet, x seconds after the rocket is launched. Which of the following systems below best represents this situation?

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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! : )
