Question 02 (b) ii 

Circle the function that solves the following differential equation 
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? 
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! 
Hint 

Try comparing the left and right hand side of the equation for the given possible solutions, . 
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.

Please rate my easiness! It's quick and helps everyone guide their studies. To solve this, we compare the left and righthand sides of the equation, 1. . Therefore, (1.) is not the answer. 2. . Therefore, (2.) is not the answer. 3. . Therefore, (3.) is not the answer. 4. . Therefore, (4.) IS the answer. 5. . Hence, and therefore, (5.) is not the answer. Finally, the in case 4 we have .
