1. The problem is to graph the piecewise function:
$$f(x) = \begin{cases} 2 - 2x & \text{if } x < 2 \\ x - 1 & \text{if } x \geq 2 \end{cases}$$
2. For piecewise functions, we graph each piece on its domain and check continuity at the boundary point $x=2$.
3. For $x < 2$, the function is $f(x) = 2 - 2x$.
- Calculate $f(2)$ from the left: $2 - 2(2) = 2 - 4 = -2$.
- Since $x=2$ is not included in this piece, the point $(2, -2)$ is an open circle.
4. For $x \geq 2$, the function is $f(x) = x - 1$.
- Calculate $f(2)$ from the right: $2 - 1 = 1$.
- Since $x=2$ is included here, the point $(2, 1)$ is a filled circle.
5. Plot the first line segment for $x < 2$ with slope $-2$ and intercept $2$ ending at an open circle at $(2, -2)$.
6. Plot the second line segment for $x \geq 2$ with slope $1$ and intercept $-1$ starting at a filled circle at $(2, 1)$.
7. The graph has a jump discontinuity at $x=2$ because the left and right limits differ.
8. Comparing the descriptions:
- Option A describes a rising line for $x < 2$ ending with an open circle near $(2, -2)$ and a falling line for $x \geq 2$ starting at $(2, -1)$, which does not match our function.
- Option B describes a falling line segment visible on the right side only, which also does not match.
9. The correct graph should have a falling line segment for $x < 2$ ending at $(2, -2)$ open circle and a rising line segment for $x \geq 2$ starting at $(2, 1)$ filled circle.
Therefore, neither A nor B matches the function correctly.
Final answer: Neither graph A nor B correctly represents the function $f(x)$ as given.
