Answer:
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.
