Kate. So four problem 15. We need to observe the given graph. So from the graph, we can see that, um, you see, the first we need to find the opening their votes for increasing and decreasing. So if we observed the given graphing our text move, guests say that approximately from negative four to negative too, dysfunction is decreasing and from elected two and zero, dysfunction will be increasing and from zero to its function will be decreasing and from 2 to 4 show would be increasing now, Part B. We need to find the need to identify the function whether the function has a local has local extreme values. So the first thing we can observe from the gravity step f negative too. And at zero and I have to will be the three local scream barrios and other. If we are looking for the absolute extreme values, we can see that at have to our function will reach the maximum. So that is the local, uh, local mixed mom we get we can get and at the end of point, our function will reach another local absolute value. So these two points will be our local. Sorry. Absolute. Ah, absolutely extreme battle
