A roller coaster begins its initial decent from a height of 400 feet and drops at
a rate of 25 feet per second, before it
reaches its next incline. Which equation
models the height of the roller coaster,
h, in terms of seconds, s?
A. h= 258 + 400
B. h= 400s - 25
C. h= (400 - 25)s
D. h = 400 - 25s

step-by-step explanation:

answer: 20

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.
