The curve C is the graph of y=Jo dt. 12-21+2 Determine -interval(s) on which the curve is concave upward. C is concave upward on: 10 Graph of y(0) The blue line in the graph above defines a linear function y = f(e) (A) Suppose that > 3 is a point that may vary on the taxis. Find the accumulated area function A(n)-() dt that calculates the net area of the shaded region on the interval (0, 2) Hint What is the area of a triangle?
