    You could evaluate the Wronskian of the three functions, or you could use the definition of linear independence.

    Isn't there a definition of linear independence in your textbook?

    Note that "independance" is not a word. Whoever wrote the problem doesn't seem to be aware of this.

    But will Wronskian easier of definition of Linear independence is more formal?

    Forum rules require that you show some effort. I don't see any effort, just question after question. And I see the question is worth 5 points. Is this a take-home test you are supposed to work yourself?
