The correct match for each graph is based on the shape and position of the quadratic function. Here are the matches:

1. Graph 1 corresponds to C) \( y = x^2 \). It is a standard parabola opening upwards with a vertex at the origin.

2. Graph 2 corresponds to A) \( y = 2x^2 \). It is a narrower parabola that opens upwards, indicating a steeper curve due to the coefficient 2.

3. Graph 3 corresponds to B) \( y = x^2 + 2 \). It is a parabola shifted upwards by 2 units.

Each of these parabolas can be identified by the vertex form and the width based on the coefficient of the \( x^2 \) term.
