Unfortunately, I am unable to find a solution to the question. However, I observed the following shown in the picture, suggesting that there may be a chance that the question is invalid. Alternatively, you can also map out f'(x) + 4f(x) and 3cos4x+1, and see if they produce the same graph. If you do find an answer, please share it with me. Thank you.
