Match each differential equation to a function which is a solution. FUNCTIONS

A$.y=3x+x^2,$

B$.y=e^{-3x},$

C$.y=sin(x),$

D$.y=x^{\frac{1}{2}}$

E$.y=6$exp$(5x),$

DIFFERENTIAL EQUATIONS

$y^{\text{'}\text{'}}+y=0$

$2x^2{y}^{\text{'}\text{'}}+3x{y}^{\text{'}}=y$

$y^{\text{'}\text{'}}+10y^{\text{'}}+21y=0$

$y^{\text{'}}=5y$
