It appears that the image contains some equations written as follows:

1. $y = x^2$
2. $y = 4$

If you are asking how to solve or interpret these, it seems like two equations are provided:

• The first equation, $y = x^2$, represents a parabola with vertex at the origin (0, 0), where $y$ is the square of $x$.
• The second equation, $y = 4$, represents a horizontal line at $y = 4$.

To find the points of intersection, we can set the two equations equal to each other since both represent $y$:

$x^2 = 4$

This simplifies to:

$x = \pm 2$

Therefore, the points of intersection are $x = 2$ and $x = -2$, which correspond to the points $(2, 4)$ and $(-2, 4)$.

Let me know if you'd like further details or explanations!

Would you like to explore:

1. The general properties of quadratic functions?
2. How to graph these functions?
3. Solving other system of equations?
4. A deeper understanding of functions and their intersection points?
5. The relationship between parabolas and lines?

Tip: When solving systems of equations, always check if both functions are linear or nonlinear, as that can affect the approach.
