The circle below is centered at the point (-1,2) and has a radius of length 3. What is its equation?
O A. (x + 2)2 + (y - 1)2 =
32
- 10
O B. (x - 1)2 + (y + 2)2 = 9
O C. (x-2)2 + (y + 1)2 =
32
O D. (x + 1)2 + (y-2)2 = 9

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

false

step-by-step explanation:

r and t.

both are 64 degrees.

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! : )
