1. Problem Description

The problem asks to find the range of the function g(x)=x2+9g(x) = x^2 + 9 for the domain {2,1,0,1,2}\{-2, -1, 0, 1, 2\}.

2. Solution Steps

To find the range, we need to evaluate the function g(x)g(x) for each value in the given domain.
* For x=2x = -2, g(2)=(2)2+9=4+9=13g(-2) = (-2)^2 + 9 = 4 + 9 = 13.
* For x=1x = -1, g(1)=(1)2+9=1+9=10g(-1) = (-1)^2 + 9 = 1 + 9 = 10.
* For x=0x = 0, g(0)=(0)2+9=0+9=9g(0) = (0)^2 + 9 = 0 + 9 = 9.
* For x=1x = 1, g(1)=(1)2+9=1+9=10g(1) = (1)^2 + 9 = 1 + 9 = 10.
* For x=2x = 2, g(2)=(2)2+9=4+9=13g(2) = (2)^2 + 9 = 4 + 9 = 13.
The range is the set of all output values, which are {13,10,9,10,13}\{13, 10, 9, 10, 13\}. We write this as a set, listing each distinct value only once. So the range is {9,10,13}\{9, 10, 13\}.

3. Final Answer

{9, 10, 13}
