Holly plays tennis on the school tennis team. She can hit a tennis ball really high in the air. She learned that the
quadratic equation below could be used to determine the
height of a tennis ball after it was hit with a tennis racket.
y = -6x2 + 36%
She defined the variables for us:
y = the height of the tennis ball in feet
x = seconds after the ball is hit with the
How long does it take for the ball to hit the ground in
seconds?
Hint: When the ball hits the ground, the height of the tennis
ball, y, is 0.

step-by-step explanation:

i am unable to solve this problem

step-by-step explanation:

true

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.

you 're wlecome! : )
