1. Find the area of the region bounded by the curves x=y³ and y=x².
2. Find the area, take the elements of the area perpendicular to the x-axis. x²-y+1=0; x-y+1=0.
3. Find the area, take the elements of the area parallel to the x-axis. y= 2x³-3x³-9x; y=x²-2x²-3x.
4. Find the area of f(x) = 3+2x-x² above the x-axis.
5. Determine the area to the left of g(y) = 3-y2 and to the right of x = -1
6. Determine the area of the region bounded by x = y²-y-6 and x = 2y +4.

- In a plant nursery, the owner thinks that the length of seedlings in a box sprayed with a new kind of fertilizer has an average height of 25cm after. One researcher randomly selected 40 such seedlings and calculated the meanheight to be 28cm and the standard deviation was 8cm.Proceed with the test using a= 0.01
