Final Answer: $(f-g)(1) = \boxed{0}$

Steps

Step 1 ：Consider the following functions: $f=\{(1,-3),(4,5)\}$ and $g=\{(-4,-2),(-2,-4),(1,-3)\}$.

Step 2 ：Find $(f-g)(1)$. The operation $(f-g)(1)$ means we need to find the value of $f(1)$ and subtract the value of $g(1)$ from it.

Step 3 ：Looking at the pairs in $f$ and $g$, we can see that $f(1) = -3$ and $g(1) = -3$. So, $(f-g)(1) = f(1) - g(1) = -3 - (-3)$.

Step 4 ：Calculate $(f-g)(1) = f(1) - g(1) = -3 - (-3)$ to get 0.

Step 5 ：Final Answer: $(f-g)(1) = \boxed{0}$
