Asking this out of spite <3 Which statement is true about the climbers’ heights?

A) Brynn was resting at a constant climbing height when Abby’s climbing height was decreasing.

B) Abby’s climbing height was decreasing when Brynn’s climbing height was increasing.

C) The heights of both climbers increased, then decreased, with no rest at a constant height.

D) Both climbers rested on the wall at a constant height for 2 minutes.

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! : )

just sum

10 + 10 = 20
