If you'd graph this function, you'd see that it's positive on [-1.5,0], and that it's possible to inscribe 3 rectangles on the intervals [-1.5,-1), (-1,-0.5), (-0.5, 1].
The width of each rect. is 1/2.
The heights of the 3 inscribed rect. are {-2.25+6, -1+6, -.25+6} = {3.75,5,5.75}.
The areas of these 3 inscribed rect. are (1/2)*{3.75,5,5.75}, which come out to:
{1.875, 2.5, 2.875}
Add these three areas together; you sum will represent the approx. area under the given curve on the given interval: 1.875+2.5+2.875 = ?
Answer: 7.3 x 10^1 & 4400000.
Step-by-step explanation: Count the place holders and just add zeros to the exponential amount.
Answer:

Step-by-step explanation:
We have been given that

We can use the formula for difference of cubes to simplify the function f(x)
difference of cubes - 

And g(x) can be written as

Thus, we have

On cancelling the common factors, we get
