  f(x) = {x ≤ 0: -x, 0 < x ≤ 4: 4 -x}

Step-by-step explanation:

The graph is of the line y = -x for x ≤ 0 and of the line y = -x +4 for the interval (0, 4].

Additional comment

There's not a really good way to specify piecewise functions in plain text. The method used in the Answer section matches that used by the Desmos online graphing calculator. It is of the form {condition: value, condition: value, ...}.

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
