Emma has a bird feeder on her balcony. A bird ate at the feeder and then flew away. The bird's vertical height is shown in the graph below.

In the graph, t represents the time, in seconds and f(t) represents the vertical height, in feet, of the bird from ground level. Emma's balcony is 21 feet above the ground. What is the lowest height of the bird and when does it occur?

The lowest height of the bird is 21 feet and occurs after 1 second.

The lowest height of the bird is 12 feet and occurs after 3 seconds.

The lowest height of the bird is 9 feet and occurs after 6 seconds.

The lowest height of the bird is 3 feet and occurs after 12 seconds.

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! : )

the option best identifies the textual evidence that supports this conclusion is c.) when an argument is over, how many weighty reasons does a man recollect which his heat and violence made him utterly forget? in order to recognize textual evidence is to identify the topic sentence where the author states the main idea. textual evidence is what supports the topic sentence or main idea of a passage.
