Answer Each Question Appropriately y=F(x)y = F ( x ) And y=G(x)y = G ( x )

Question 286

Multiple Choice

Answer each question appropriately.
-If differentiable functions y=F(x) y = F ( x ) and y=G(x) y = G ( x ) both solve the initial value problem dydx=f(x) ,y(x0) =y0\frac { d y } { d x } = f ( x ) , \quad y \left( x _ { 0 } \right) = y _ { 0 } , on an interval I, must F(x) =G(x) F ( x ) = G ( x ) for every xx in I? Justify the answer.


A) F(x) = G(x) for every x in I because integrating f(x) results in one unique function.
B) F(x) and G(x) are not unique. There are infinitely many functions that solve the initial value problem. When solving the problem there is an integration constant C that can be any value. F(x)
And G(x) could each have a different constant term.
C) F(x) = G(x) for every x in I because when given an initial condition, we can find the integration constant when integrating f(x) . Therefore, the particular solution to the initial value problem is
Unique.
D) There is not enough information given to determine if F(x) = G(x) .
