Determine the area of the region bounded by the given function, the $$x$$-axis, and the given vertical lines. The region lies above the $$x$$-axis. $$f(x)=2\sqrt{x},x=1\text{ and }x=9$$ Find the area of the region bounded by $$f(x)=x^2?6x+8$$, the $$x$$-axis, and the lines $$x=3$$ and $$x=6$$. Find the area bounded by the function $$f(x)=0.4x^3?0.5x^2+10$$ the $$x$$-axis, and the lines $$x=1$$ and $$x=6$$. Round to 2 decimal places, if necessary. $$A=$$
