    2. Solve the differential equation

    𝑑𝑦/𝑑𝑡 =3𝑡2/𝑦 with initial condition

    𝑦(2) = 0.

    y=ln15ty=\ln\left|15t\right|

    y=16t3y=16t^3

    y = 2t316y\ =\ \sqrt{2t^3-16}

    y=2t316y=2t^3-16

    Which of the following is the solution to the differential equation  dydx=x2y\frac{dy}{dx}=\frac{x^2}{y}  with the initial condition y(3) = -2?

     y=2e(9+x33)y=-2e^{\left(-9+\frac{x^3}{3}\right)}  

     y=2x33y=\sqrt{\frac{2x^3}{3}}  

     y=2x3314y=\sqrt{\frac{2x^3}{3}-14}  

     y=2x3314y=-\sqrt{\frac{2x^3}{3}-14}
