Step-by-step Solution
To sketch the graph of the function \( y = |x + 1| \), you can follow these steps:
1. **Identify the Vertex**: The expression inside the absolute value, \( x + 1 \), equals zero when \( x = -1 \). This point, \( (-1, 0) \), is the vertex of the V-shaped graph.
2. **Determine the Direction**: Since the absolute value function opens upwards, the graph will extend upwards from the vertex.
3. **Find Additional Points**: Choose a few values of \( x \) to find corresponding \( y \) values:
- For \( x = -2 \): \( y = |-2 + 1| = | -1 | = 1 \) → Point: \( (-2, 1) \)
- For \( x = 0 \): \( y = |0 + 1| = |1| = 1 \) → Point: \( (0, 1) \)
- For \( x = -3 \): \( y = |-3 + 1| = |-2| = 2 \) → Point: \( (-3, 2) \)
4. **Plot the Points**: Plot the points \( (-1, 0) \), \( (-2, 1) \), \( (0, 1) \), and \( (-3, 2) \) on the graph.
5. **Draw the V-Shape**: Connect the points with straight lines, forming a V shape that opens upwards.
In summary, the best statement to describe the method for sketching the graph of \( y = |x + 1| \) is: **Identify the vertex, determine the direction of the graph, find additional points, and then plot and connect these points to form the V shape.**
Quick Answer
To sketch the graph of \( y = |x + 1| \), identify the vertex, find additional points, and connect them to form a V shape.
