# Graphing \( y = ax^2 \)

**Objective:**
Understand how the graph of \( y = ax^2 \) changes when the coefficient \( a \) increases or decreases, and whether \( a \) is positive or negative.

**Instructions:**
Graph each pair of functions on the set of axes provided.

**Equations and Graphs:**

1. \( y = x^2 \)
   \( y = -x^2 \)
   
   - These equations are to be graphed on the first set of axes.
   - The graph of \( y = x^2 \) is a parabola opening upwards.
   - The graph of \( y = -x^2 \) is a parabola opening downwards.
   
2. \( y = 2x^2 \)
   \( y = -2x^2 \)
   
   - These equations are to be graphed on the second set of axes.
   - The graph of \( y = 2x^2 \) is a parabola opening upwards, which is narrower than the graph of \( y = x^2 \).
   - The graph of \( y = -2x^2 \) is a parabola opening downwards, which is narrower than the graph of \( y = -x^2 \).
   
3. \( y = \frac{1}{2}x^2 \)
   \( y = 3x^2 \)
   
   - These equations are to be graphed on the third set of axes.
   - The graph of \( y = \frac{1}{2}x^2 \) is a parabola opening upwards, which is wider than the graph of \( y = x^2 \).
   - The graph of \( y = 3x^2 \) is a parabola opening upwards, which is narrower than the graph of \( y = x^2 \).

**Graphical Explanation:**

Each of the three provided sets of axes feature an x-y coordinate plane:

- The x-axis and y-axis extend from -4 to 4 in both directions.
- The first set of axes is intended for plotting \( y = x^2 \) and \( y = -x^2 \).
- The second set of axes is for \( y = 2x^2 \) and \( y = -2x^2 \).
- The third set of axes is for
