Given that f(x)=x^2-3 and g(x)=4x+1 find (f-g)(-1) if it exists. Select the correct choice below and, if necessary,fill in the answer box to complete your choice. A. (f-g)(-1)=square (Simplify your answer.) B. The value for (f-g)(-1) does not exist.

To find $$(f-g)(-1)$$ , we need to evaluate $$f(-1)$$ g(-1) $$first. Given$$ f(x)=x^{2}-3 $$, we can substitute$$ x=-1 $$to get$$ f(-1)=(-1)^{2}-3=1-3=-2 $$. Given$$ g(x)=4x+1 $$, we can substitute$$ x=-1 $$to get$$ g(-1)=4(-1)+1=-4+1=-3 $$. Now, we can find$$ (f-g)(-1) $$by subtracting$$ g(-1) $$from$$ f(-1) $$:$$ (f-g)(-1)=f(-1)-g(-1)=-2-(-3)=-2+3=1 $$. Therefore, the correct choice is A.$$ (f-g)(-1)=1$.
