Graph Parabola
1. **Problem:** Sketch a rough graph of the function $$y = x^2$$.
2. **Formula and Explanation:** The function $$y = x^2$$ is a quadratic function representing a parabola.
- The graph is symmetric about the y-axis.
- The vertex (minimum point) is at the origin $$(0,0)$$.
- As $$x$$ increases or decreases, $$y$$ increases quadratically.
3. **Key points to plot:**
- At $$x=0$$, $$y=0^2=0$$.
- At $$x=1$$, $$y=1^2=1$$.
- At $$x=-1$$, $$y=(-1)^2=1$$.
- At $$x=2$$, $$y=2^2=4$$.
- At $$x=-2$$, $$y=(-2)^2=4$$.
4. **Shape description:**
- The graph is a U-shaped curve opening upwards.
- It passes through points $$(0,0), (1,1), (-1,1), (2,4), (-2,4)$$.
5. **Summary:**
- The parabola $$y = x^2$$ has vertex at the origin.
- It is symmetric about the y-axis.
- The graph opens upwards and gets steeper as $$|x|$$ increases.
Final answer: The graph of $$y = x^2$$ is a parabola with vertex at $$(0,0)$$ opening upwards.
