Which equation represents a circle that contains the point (-2, 8) and has a center at (4,0)?
Distance formula: V(x2 - x2)2 + (12 – - 72
(x – 4)2 + y2 = 100
(x-4)2 + y2 = 10
x2 + (y – 4)2 = 10
x2 + (-4)2 = 100

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

(3x-8) or (3x+8)

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! : )
