The function h(x) =x^2+3 and g(x)=x^2-6. if g(x)=h(x)+k, what is the value of k?

k = -9

Step-by-step explanation:

Subtracting 9 from h(x) =x^2+3 translates the graph of x^2 + 3 downward 9 units, creating the new function g(x)=h(x)+k, with k = -9.

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
