In which domain does the function decrease?
Remember that the function increases when X values and Y values increase simultaneously.
On the other hand, the function decreases when X values increase and Y values decrease simultaneously.
According to the given value table, we can see that in the domain whereX values increase and Y values decrease simultaneously.
Therefore, the function decreases in the domain where
Does the function in the graph decrease throughout?
Decreasing means the function goes down as you move right (x increases). Negative values just means y < 0. A function can decrease while staying positive!
Look at the x-values on top and y-values on bottom. Follow them from left to right to see if y is getting bigger (increasing) or smaller (decreasing).
The question asks where the function decreases, not increases! When , y goes from 0 to 9, so it's increasing in that domain.
Yes! Functions can have multiple decreasing intervals. Always check each section of the domain separately and list all intervals where the function decreases.
If consecutive y-values are equal, the function is constant (neither increasing nor decreasing) in that interval. Look for sections where y actually changes.
