From the image, we have a graph of a curve that appears to start at $(0, -6)$ and extends to the right as $x$ increases, continuing indefinitely in that direction.

Domain:

The domain refers to the set of all possible $x$-values for which the function is defined. Since the curve starts at $x = 0$ and extends to the right, the domain includes all $x \geq 0$.

Domain: $[0, \infty)$

Range:

The range refers to the set of all possible $y$-values that the function takes. The curve starts at $y = -6$ and increases as $x$ increases. Since the curve continues indefinitely upwards, the range includes all $y \geq -6$.

Range: $[-6, \infty)$

Would you like more details, or do you have any questions?

Here are some related questions you can consider:

1. How would the domain change if the curve started at $x = -3$ instead of $x = 0$?
2. How can you determine the range of a function without a graph?
3. What is the significance of the domain and range in real-world applications?
4. How would the range change if the curve approached a maximum $y$-value?
5. Can you identify if this graph represents a specific function type, such as a square root or exponential function?

Tip: Always check for any restrictions on the $x$-values or $y$-values when determining domain and range from a graph.
