Math Problem Statement
Which table shows a function that is increasing only over the interval (–2, 1), and nowhere else?
Solution
To determine which table shows a function that is increasing only over the interval (-2, 1) and nowhere else, let’s break this down:
- A function is increasing on an interval if the values of increase as moves from left to right in that interval.
- Outside the interval , the function should not be increasing. It may be constant or decreasing.
Characteristics of the correct table:
- increases only for values between and .
- does not increase for or .
- For points outside the interval , values must either stay the same or decrease.
Do you have a specific set of tables or values? If not, I can help generate a table for this situation. Let me know!
If you’d like, I can explain more about functions and intervals. Here are 5 related questions:
- How do you test if a function is increasing or decreasing from a graph?
- What is the difference between increasing and strictly increasing?
- Can a function be increasing at a single point, like ?
- How would a derivative help verify whether a function increases on a specific interval?
- What happens if a function is constant outside ?
Tip: When checking for increasing intervals, focus on the pattern of the outputs () and how they change as the inputs () progress.
