In below Problems, use properties of definite integrals.
1. How does f-3-1x√x2+1dx compare with does f-1-3x√x2+1dx
2. If f o-1x3dx=-1/4 and f 10 x3 dx=1/4, what dose f 1-1 x3 dx equal?
3. If f21 (2x-x2) dx = 2/3 and f42 (2x - x2) dx = -20/3, what dose f41 (x2 -2x) dx equal?
4. If f21 (2x-x2) dx = 2/3, what dose f21 6(2x-x2) dx equal?
5. Evaluate f44 √x2-2dx.
