Look at the data in the table. x y 2.4 9 7.2 28 7 24 8.3 35 3.1 9 7.2 30 9 32 which graph shows the line of best fit for this data?

Given table

______

x         y

______

2.4     9

7.2     28

7         24

8.3      35

3.1      9

7.2     30

9        32

_________

So, the coordinates on the graph (2.4, 9), (7.2, 28), (7, 24), (8.3, 35),  (3.1 , 9), ( 7.2, 30), (9, 32).

The first graph represents the line of best fit.

The definition of line of best fit " A line of best fit is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points.".

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! : )
