hint: take the derivative of both sides

I'm not sure I understand it properly but my answer is: since $\int\limits_{0}^{x} f(t) dt = 4x^7 + x^4 + 3x$ then you just need to figure out what the intagram (or f(t)) is. To cancel an integral, we can just differentiate, meaning f(x) is just the derivative of $4x^7 + x^4 + 3x$ which is just: $28x^6 + 4x^3 +3$
