The number of foreign adoptions in a country has declined in recent​ years, as shown in the table. ​a) Use a graphing calculator to fit​ quadratic, cubic, and quartic fuctions to the data. Let x represent the number of years after 2003. Using R2​-values, determine which function is the best fit.
​b) Using the function found in part​ (a), estimate the number of foregin adoptions in 2014.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
