Is the interval from negative infinity to -1 increasing or decreasing?
The interval from negative infinity to -1 is decreasing
The interval from negative infinity to -1 is decreasing.
In mathematics, when we talk about an interval being increasing or decreasing, we are referring to the behavior of the values within that interval as we move along the number line from left to right.
In this case, the interval from negative infinity to -1 includes all real numbers that are smaller than or equal to -1. As we move from left to right along the number line, the numbers become smaller and smaller, approaching negative infinity. Therefore, the values within this interval are decreasing.
