For what x-values is the graphed function decreasing? all x-values, except 4 no x-values x > 4 x < 4

Given function is decreasing for all x-values , except 4.

Step-by-step explanation:

We are given with a graph of the function and we are asked to find x-values for which function is decreasing.

We will say a function is decreasing If as x increases(from left to right) y decreases(goes down).

The given graph has 2 regions till x=4 and after x=4

Till x=4, if we see the graph from left to right, graph is going down, which means it is decreasing.

After x=4 also, as x goes from left to right, graph is going down, which means it is decreasing after x=4 also.

Hence the given function is decreasing for all x-values except x=4.
