A quick quiz on linear independence.

Is the set of vectors {(1, 2), (2, 4), (-3, 5)} linearly independent? Why or why not?

Yes, because the only way a(1,2)+b(2,4)+c(-3,5) = (0,0) is if a = b = 0.

Yes, because there are infinitely many solutions to the equation a(1,2)+b(2,4)+c(-3,5) = (0,0).

No, because the only way a(1,2)+b(2,4)+c(-3,5) = (0,0) is if a = b = 0.

No, because there are infinitely many solutions to the equation a(1,2)+b(2,4)+c(-3,5) = (0,0).

If W(x)=0 for all x in I, then the functions are linearly independent.

If W(x) is not zero for any x in I, then the functions are linearly independent.

If W(x) is not zero for at least one x in I, then the functions are linearly independent.
