Compute the tangent line $L(x)$ through $f(100)$, then compute $L(103)$.

Calculate the slope $f’(100)$ of the tangent line. You also know a point if it, namely $(100,f(100))$. Now write down the line’s equation and plug in $103$.

I think $f(x+Delta x)-f(x)approx f'(x),Delta x$. And the approximation would be better for smaller $Delta x$.
In this case, you have $f(x)=2x^2$. Take $x=100$ and so $Delta x=3$.
You may then approximate $f(103)approx f(100)+f'(100)cdot 3$.
