need some help with these questions

1. Determine the area of the region enclosed by the following: A) f (x) = =x+5, g(x) = x+-, over the interval [1,5]. B) f (x) = x, g(x) =x4. C) f(x) = sinx, g(x) = cosx, from [, 2x].2. Find the area of the region using A) absolute value & B) respect to y-axis approach for: N W 1(x ) - JX g(x) = - 2 1 2 3 X A) Respect to x B) Respect to y 3. Graph, then shade and find the area between the two curves by integrating over either the x- or y-axis, whichever seems more convenient, for the following. A) y = x2 - 3x + 2, y=x3-2x2-x+2 B ) x = yz , x = y+2
