7. Given the graph of y = N " (x) , the second derivative of N (x) , answer the following questions about the original lnction N(x) : Place 2 arrows on the graph pointing upward. a} On what interval(s} is NU) increasing? b) On what interval{s} is N{x) decreasing? c) On what interval(s) is N (x) concave up? d} On what interval{s} is NU!) concave down? e} Does N01) have a relative maximum? If so, where? f} Does N (x) have a relative minimum? If so, where? g} Does N(x) have an inection poinb(s}? If so, where? Ii) What is the slope of N{x} at x =1? i} What is the value of N (0) ? j} In the interval [3,5] , at what xvalue is N (x) decreasing most lapidly
