*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
