Identify the key features of the quadratic. NO SPACES WHEN YOU TYPE YOUR ANSWERS. If there is NONE, type NONE.

f(x)=x2−2x−3

Vertex:

x-intercepts (write them as an ordered pair (x, y)):

y-intercept:

Axis of symmetry (write as x=#, for example x=3):

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! : )

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
