Finding Decreasing Intervals: Analyzing Function Values from -2 to 10

Let's remember that a function is increasing if both $x$ values and $y$ values are increasing simultaneously.

A function is decreasing if $x$ values are increasing while $y$ values are decreasing simultaneously.

According to the value table, we can see that in the domain x < 2 , the$x$ values are increasing while the $y$ values are decreasing simultaneously. Therefore, the function is decreasing in the domain x < 2 .
