Use technology to determine the correlation coefficient, rounded to two decimal places, between the percentage of people in a country who are literate and the percentage who are undernourished. Use technology to find the equation of the regression line for the percentage who are literate and the percentage who are undernourished. Round "m" and "b" to two decimal places. Use technology to determine the percentage of people, to the nearest percent, can we anticipate are undernourished in a country where 60% of the people are literate?

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! : )

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
