3. Determine the Reflected Function: To find the reflection about the origin, we need to find $-f(-x)$. First, let's find $f(-x)$ by substituting $-x$ for $x$ in the original function:
$$f(-x) = -((-x)+2)^2 + 1$$
$$f(-x) = -(-x+2)^2 + 1$$
Now, we multiply this by $-1$ to get $-f(-x)$:
$$-f(-x) = -[ -(-x+2)^2 + 1 ]$$
$$-f(-x) = -[ -(x-2)^2 + 1 ]$$
$$-f(-x) = (x-2)^2 - 1$$
- For $x = 0$:
$$-f(-0) = (0-2)^2 - 1$$
$$-f(0) = (-2)^2 - 1$$
$$-f(0) = 4 - 1$$
$$-f(0) = 3$$
- For $x = 1$:
$$-f(-1) = (1-2)^2 - 1$$
$$-f(-1) = (-1)^2 - 1$$
$$-f(-1) = 1 - 1$$
$$-f(-1) = 0$$
- For $x = 2$:
$$-f(-2) = (2-2)^2 - 1$$
$$-f(-2) = (0)^2 - 1$$
$$-f(-2) = 0 - 1$$
$$-f(-2) = -1$$
