f(x) = x^2/(x^2 β 9)Where is the auction increasing and decreasing? Critical numbers= 2
Accepted Solution
A:
Answer:Step-by-step explanation:The first thing to do is get a graph of the function if you can. The graph helps you see the following.The critical points are at +/- 3The graph is increasing from -β β€x<-3 Watch that you do not include - 3The graph is increasing form -3<x<0The graph is decreasing from 0<x<3The graph is decreasing from 3<x<β
