Use the graph below for this question: graph of parabola going through negative 2, 1 and 0, 1. what is the average rate of change from x = −2 to x = 0? 1 0 −2 2

The average rate of change from x= -2 to x=0 is 0 (second option)

Step-by-step explanation:

Point A=(-2, 1)=(a, f(a))→a=-2, f(a)=1

Point B=(0, 1)=(b, f(b))→b=0, f(b)=1

Average rate of change from x=a to x=b:

r=(f(b)-f(a)) / (b-a)

Replacing the given values:

r=(1-1) / (0-(-2))

r=(0) / (0+2)

r=(0) / (2)

r=0

x+14

step-by-step explanation:

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
