All real numbers that are greater than or equal to -1.5 and less than 9.2

So in order to answer this, let us put x as the real numbers. So based on the given values above, we can represent x this way:  −1.5 ≤x <9.2
Negative 1.5 is less than or equal to x and 9.2 is greater than or equal to x. Hope this is the answer that you are looking for.
