The answer is B) 2 and 3
When you do a Riemann's sum, you split the interval into columns. In choice 3 we are told that there are 4 equal subdivisions meaning that each of the 4 columns are 1 wide. Since it is a left Riemann's sum we add the height of the column where the LEFT side crosses the curve. For [-1, 0], the height is -1, for [0, 1] it is 0, for [1, 2] it is 2, and for [2, 3] it is 3. Now add the heights together to get 4. Then you multiply by the width, but since the columns are 1 wide, the answer is still just 4.
Answer: b. Collaboration that includes diverse backgrounds and perspectives can eliminate the need for software testing.
Explanation:
While collaborating and creating a team that includes diverse backgrounds and perspectives is good for anticipating the needs of the people that will use the software as well as avoid bias, it does not take away the need for software testing.
