 ## Corrections and clarifications:
 
-* None yet.
+* **4/27/2023 - 12:00 PM**: For both Question 17 and Question 18, the testing script is faulty. You will need to swap the `x` and `y` arguments to pass the autograder. This does not cause any logical errors, and you can proceed to plot the graphs with the correct `x` and `y` axes as mentioned in the question.
