It seems like you're referring to a situation where a value or function is increasing over a certain interval, specifically from $-7$ to $0$. To clarify:

• If you're talking about a function $f(x)$, and you're saying it's increasing from $-7$ to $0$, this would mean that for all $x_1, x_2$ within this interval (where $-7 \leq x_1 < x_2 \leq 0$), the function satisfies $f(x_1) < f(x_2)$. In other words, as $x$ moves from $-7$ to $0$, the values of $f(x)$ are getting larger.

If you meant something else, such as a number line or another type of context, please clarify!

Would you like details on this concept, or do you have any other questions? Here are some related questions that might interest you:

1. How do you determine if a function is increasing or decreasing?
2. What does it mean for a function to be strictly increasing?
3. How do you find the intervals where a function is increasing or decreasing?
4. What role do the first and second derivatives play in identifying increasing and decreasing intervals?
5. How do critical points relate to increasing and decreasing intervals?

Tip: Remember that a function is increasing on an interval if its derivative is positive over that interval.
