The scatter plot shows how the cooking time for a beef roast is related to its weight. which statement is not supported by the trend in the scatter plot?
a. each additional pound adds about 12 hour of cooking time.
b. an 11-pound roast will take about 4 hours to cook.
c. a 16-pound roast will take about 6.5 hours to cook.
d. each additional pound adds about one hour of cooking time.

the statement that is not supported by the trend in the scatter plot is d) each additional pound adds about one hour of cooking time.

Step-by-step explanation:

The last statement is not supported by the scatter plot, because the ratio shown is not 1:1, that is, per one hour cooking time one more pound, that is not true.

We can take the first two points as a counterexample that demonstrate this. The first point is (11;4), that is, a 11 pounds beef takes 4 hours to be cooked, then the second point is (12;4.5), that is, a 12 pounds beef takes 4.5 hours to be cooked, just increase half an hour, therefore, the last option is not support by the data showed in the scatter plot.

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! : )
