Optimizing Functions of One Variable: Cost Minimization Exercise 2

what is this, before it happens i have deleted the 2 files contains on lab which is [C2_W1_Assignment.ipynb] and [w1_unittest.py]. Why i do that, because i got error when im finishing my grading lab on exercise 2 where i got and error about parameter which is located on w1_unittest.py file so i changed the file on unittest. Then i finish my lab that already passed all of the exercise, but i got 0 grade just like on the foto. Thank you for the help

You are not meant to be tampering with the unitests they are part of the grader, reset the entire workbook and try again, you must be solving it wrong somewhere and that why you get the errors!

Okayy already fixed, thank youu

hey, how to reset the entire workbook?
