In this problem we have to determine whether the functions are linearly independent or not.
00:05
So let us start with the solution.
00:08
We firstly suppose that let fx is equal to 1 plus 3x, gx is equal to 1 minus 3x is equal to 1 minus 5 times x squared.
00:30
So we have f -dash -x is equal to 3.
00:37
Similarly, g -dash -x will be equal to minus 3 and h -dash -x will be equal to minus 10x.
00:48
Then we again differentiate the above functions and we get f -tabble -dash -x is equal to 0.
00:54
G -d -dablish -x is equal to 0 and h -tabl -dash -x is equal to minus 10.
01:02
Now we will find the bronze gn, bronzkyen denoted by w, and it will be equal to determinant of fx, gx, hx, and in the next row we will have f -dash -x, g -dash -x and h -dash -x, and then we have f -double -dash -x, and then we have f -double -dash -x, and h -double -dash -x, and h -double -dash -x, and h - we'll find this determinant and it will be equal to determinant of 1 plus 3x, 1 minus 3x, 1 minus 5 times x squared 3 minus 3 minus 3 and minus 10x, 0 0 and minus 10...
