Question details

uppose that

f(x) = ln(6+12)



(A) Use interval notation to indicate where f(x) is concave up.
Note: When using interval notation in WeBWorK, you use I for \infty , -I for -\infty , and U for the union symbol. If there are no values that satisfy the required condition, then enter "{}" without the quotation marks.

Concave up:


(B) Use interval notation to indicate where f(x) is concave down.
Concave down:


(C) Find all inflection points of f . If there are no inflection points, enter -1000. If there are more than one, enter them separated by commas.
Inflection point(s) at x =
