Is the set of functions   linearly dependent or linearly independent on (−∞, ∞)?

Is the set of functions   linearly dependent or linearly independent on (−∞, ∞)? Discuss.

Functions will only be Linearly dependent when the meet these requirements:

1. Within the functions intervals of , we will have multiple constants ‘c’. All of our constants can equal 0 but there must be at least one constant, c > 0. If the functions contains all zeros then it is linearly independent.
