The graph of f is shown in the figure. The shaded region 4 has an area of 1.5, and So f(x) dx = 3.5. Use this information to fill in the blanks. (a) f(x) dx = Jo 6 (b) f(x) dx = 2 6 (c) If(x) | dx = A 0 B X 2 3 4 5 6 d) -2f(x) dx = 0 6 (e) [2 + f(x) ] dx = (f) The average value of f over the interval [0, 6] is
