Ugh... seems so simple but I really muddled up my answers so badly that I can't find my footing anymore, I think. A set of actually correct answers I can compare mine to would be greatly appreciated. Some of these multi-part questions in this workset don't tell you what's wrong until you get all of them right which is complete bogus, in my opinion. I HATE 'EM.
If I were given an actual function for this it'd be so easy... :/
The Question:
For each of the labelled x-values on the graph, classify the corresponding point on the graph of y=f(x) as one of the following: MAX, MIN, INFL, INT (short for maximum, minimum, inflection point, x-intercept)
A:
B:
C:
D:
E:
For each of the following intervals, classify whether the graph of y=f(x) is INC or DEC over that interval (short for increasing or decreasing).
(−∞,A):
(A,B):
(B,C):
(C,D):
(D,E):
(E,∞):
For each of the following intervals, classify whether the graph of y=f(x) is CU or CD over that interval (short for concave up or concave down).
(−∞,A):
(A,B):
(B,C):
(C,D):
(D,E):
(E,∞):
The graph in question:
My answers:
These are all probably horribly, horribly, wrong, but I got frustrated and started shopping around for similar examples and got nowhere. I probably just need to start over. Please help
