Final Answer: $f(-2) = \boxed{14}$.

Steps

Step 1 ：The function $f(x)=x^{2}-3 x+4$ is a quadratic function. We can substitute $x$ with $-2$ directly into the function.

Step 2 ：After substituting $x$ with $-2$ in the function $f(x)=x^{2}-3 x+4$, we get $f(-2) = 14$.

Step 3 ：Final Answer: $f(-2) = \boxed{14}$.
