$$y^{″}(x)-f(x)y(x)=0$$ ✗ Mathematica : cpu = 0.120945 (sec), leaf count = 0 , could not solve

DSolve[-(f[x]*y[x]) + Derivative[2][y][x] == 0, y[x], x]

✗ Maple : cpu = 0. (sec), leaf count = 0 , result contains DESol

$$\{y\left(x\right)=\mathit{D}\mathit{E}\mathit{S}\mathit{o}\mathit{l}(\{-f\left(x\right)\mathit{\_}\mathit{Y}\left(x\right)+\frac{{\mathrm{d}}^2}{\mathrm{d}{x}^2}\mathit{\_}\mathit{Y}\left(x\right)\},\left\{\mathit{\_}\mathit{Y}\left(x\right)\right\})\}$$
