Ordering Second Derivative Values

Consider the particular solution $y=\sqrt{4x^2+25}$ to the differential equation $\frac{dy}{dx}=\frac{4x}{y}$. The second derivative is $\frac{d^2y}{dx^2}=\frac{100}{(\sqrt{4x^2+25})^3}$. The approximate values of the second derivative at $x=0, 1, 2,$ and $3$ are $0.8, 0.642, 0.382,$ and $0.210$, respectively. Which of the following lists the x-values in order from the smallest value of $\frac{d^2y}{dx^2}$ to the largest value?
