A calculus problem by Nishant Rai

$\begin{aligned} I_1 &=& \int _{ 1 }^{ 3 }{(x^2 + x + 3)f(x^3 - 2x^2 - 5x +2020)} \ dx \\ I_2 &=& \int _{ 1 }^{ 3 }{(4x^2 - 3x - 2)f(x^3 - 2x^2 - 5x +2020)} \ dx \\ \frac{2I_1}{3I_2} &=& \ ? \end{aligned}$

To clarify: " $\in{(a,b)}$ " implies that your answer must be in between $a$ and $b$ exclusive.
