Use the Wronskian to determine if the given functions are linearly independent on the
indicated interval.
f(x) = 19, g(x) = x, h(x) = 5x²; the real line
Select the correct choice below and, if necessary, fill in the answer box to complete your
choice.
(Simplify your answer.)
A. The Wronskian W(f, g, h) =
and h(x) are linearly dependent.
As W is identically 0 on the real line f(x), g(x)
B. The Wronskian W(f, g, h) =. As W is never 0 on the real line f(x), g(x) and h(x)
are linearly dependent.
C. The Wronskian W(f, g, h) =
are linearly independent.
OD. The Wronskian W(f, g, h) =
As W is never 0 on the real line f(x), g(x) and h(x)
As W is identically 0 on the real line f(x), g(x)
and h(x) are linearly independent.
