Estimate the area under the curve.
y=-x^2+3x+2
Do you mean between the curve and x-axis? If so,
Area = 11.6821
-----------------
0 is less than or equal to x is less than or equal to 4
Use four partitions.
Is that another problem? The parabola above crosses the x-axis at
x = -1.5 + sqrt(17)/2 and at
x = -1.5 1 sqrt(17)/2
At x = 4, it's below the x-axis.
-----------------
You can graph this and see on the FREE software from www.padowan.dk.com/graph/ and it will calculate the area, too.
