Determine the range of the following graph: 12
11
10
9
8
7
6
5
4
3
2
-12-11-10 -9 -8 -7 -6 -5 -4 -3 -2 -1
1 2 3 4 5 6 7 8 9 10 11 12
- 2
-9
-10
Can somebody help me with this question ? T. i.a (:

Step-by-step explanation:

Range is all possible y values a function can have. Look at the y axis. So let find the max/ min y value the function can have. The max y value is 1, and the minimum y value is -4. All the x Intervals fall between -4, and 1. Since we have solid dot we include the -4 and 1.

So the notation for this is

or

[-4,1]

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
