a) from the given graph, B will be answer.
as the mentioned parts are only increasing with concave slopes.
b)C will be answer, as here rate of rate of change of f(x) is negative.
c) A will be the answer as between those interval f(x) has only positive slopes.
d) point of inflection : x=e....as from here f(x) is only increasing.
