Please finish all parts of the questiona dn double check your work before you post it.
Verify that each function is a solution to given differential equation. a. \( y^{\prime \prime}-y=0, y_{1}(t)=e^{t}, y_{2}(t)=\cosh (t) \) c. \( t y^{\prime}-y=t^{2}, y_{1}(t)=3 t+t^{2} \) b. \( y^{I V}+4 y^{\prime \prime \prime}+3 y=t, y_{1}(t)=\frac{t}{3}, y_{2}(t)=\frac{t}{3}+e^{-t} \)
