Select the statement that correctly describes a normal distribution. a. It is a negatively skewed distribution, as the extreme values are less than the median. b. It is a symmetric distribution, as the mean and the median are the same. c. It is a positively skewed distribution, as the extreme values are greater than the median. d. It is a uniform distribution, as all of the values have equal frequency.

the discriminant is 64 + 4*1*12 = 112

this is prime.

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! : )
