I have to find the dimension of the vector subspace spanned by this set.

Im not sure where to start, I do know how to solve other problems asking the same question just different function. Any help would be greatly appreciated.

thanks

Assume we mean C(R) the vector space of real valued functions (over R) then you have to vectors e^x and e^2x. They span a space of at most dimension two. Are they linearly independent (as funtions)? Ie are the real numbers u and v such that ue^x+ve^2x is the zero vector in the vector space. Hopefully you know what the zero vector is and see that obviously these are linearly independent vectors
