The given image contains a graph that appears to represent part of a function. The domain of a function consists of all the possible x-values for which the function is defined.

Observing the Graph:

• The function appears to be a sideways parabola (possibly part of a relation like $x = y^2$).
• The leftmost visible point is around $x \approx -6$, and it extends to the right until approximately $x = 0$.
• Therefore, the domain of this function is approximately $-6 \leq x \leq 0$.

Would you like a more detailed explanation of how to determine the domain from graphs?

Tip: The domain represents all valid inputs (x-values), while the range represents all possible outputs (y-values).
