The domain of a function is representative of which one of the following characteristics of the function? a. all possible outputs of the function b. all possible f(x) values of the function c. all possible (x, y) coordinates d. all possible inputs of the function

D. all possible inputs of the function

Step-by-step explanation:

Lets look at the options one by one

A. all possible outputs of the function

This is not the correct option because the possible outputs are range of the function

B. all possible F(x) values of the function

Not correct because the f(x) values are the output of the function.

c. all possible (x, y) coordinates

This is also not correct because domain only consists of all the values of independent variable that make the function produce some output

D. all possible inputs of the function

This is the correct answer because domain is the set of all values of independent variable for which the function is not undefined ..

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
