Question

Identify the graph of y=0.4(x-1)2. Then identify the vertex and axis of symmetry.

The image presents four graphs of quadratic functions displayed on a coordinate plane with a grid. Each graph features a parabolic curve, and there is a selection bubble next to each one.

1. **Top Left Graph:**
   - This is a standard upward-opening parabola centered at the origin.
   - The vertex of the parabola is at the point (0, 0).
   - The curve passes through points approximately (-2, 4) and (2, 4).
   - The parabola is symmetric with respect to the y-axis and increases as it moves away from the vertex.

2. **Top Right Graph:**
   - This parabola is narrow and opens upward.
   - The vertex is slightly above the x-axis, approximately at point (0, -2).
   - The arms of the parabola point upwards and converge more steeply than the other graphs.

3. **Bottom Left Graph:**
   - Similar to the top left graph, this parabola opens upwards.
   - The vertex is also at the origin (0, 0).
   - The parabola is symmetric about the y-axis and passes through points (-2, 4) and (2, 4).

4. **Bottom Right Graph:**
   - This is a downward-opening parabola.
   - The vertex is at the origin (0, 0).
   - The parabolic curve symmetrically descends on both sides as it moves away from the vertex.
   - It crosses the y-axis at the origin and appears symmetric across this axis.

Each graph is plotted on a grid with axes labeled from -4 to 4 for both x and y. The grid helps to visualize the symmetry and dimensions of the parabolas.
