Using function concepts, it is found that the domain in which the function is decreasing is: [tex](-\infty,2][/tex]
-------------------------------
- The domain of a function is composed by it's input values, in a graph the x-values.
- The function is decreasing when y decreases as x increases.
-------------------------------
- The arrows in the graph indicates that the function goes from negative infinity to positive infinity.
- The graph, that is, y is falling for x between negative infinity and 2.
- Thus, the domain for which the function is decreasing is given by: [tex](-\infty,2][/tex]
