Extracted text: 6. Which of the following functions are never a solution to the differential equation y" + 2y' – 8y = 5e¬4 no matter the value of the constant A? (For example, y = Ae* is not a solution, no matter what value A takes; so y = Ae“ would be a correct answer). Mark all correct answers. a) y = Ae2* b) y= Ae¬Az c) y= Axe²# d) y= AxerAx e) y= e# +er4= + Aver4"
