Over which interval is the graph of the parent absolute value function f(x)=|x| decreasing?
(–∞, ∞)
(–∞, 0)
(–6, 0)
(0, ∞)

(–∞, 0)

Step-by-step explanation:

The graph of the absolute value parent function f(x) = |x| is shown in the attached diagram.

We can clearly see that from -∞ to 0, the function is decreasing and from 0 to +∞, it is increasing. This is the basic, parent absolute value function.

THe questions asks, when is it decreasing, so clearly, it is from -∞ to 0.

This is the answer.

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
