Enter a letter and a number for each formula below so as to define a continuous function.

The letter refers to the list of equations and the number is the value of the function f at 1.
Letter, Number
$$\displaystyle \frac{ \sin(2x-2 ) }{ x-1} + 1$$ when $$x< 1$$
$$\displaystyle \frac{ x^{2}-6x+5 }{ |x-1| }$$ when $$x< 1$$
$$\displaystyle (x-1)\sin\left( \frac{1}{x} \right)$$ when $$x < 1$$
$$x^{3}-2x^{2}-1$$ when $$x < 1$$

A. $$\displaystyle \frac{ x^{2} - 4x+3 }{ x-1 }$$ when $$x > 1$$
B. $$\displaystyle \frac{1- \cos(4\pi x) }{ 2\pi^2 (x-1)^2}$$ when $$x > 1$$
C. $$-x^{2}+4$$ when $$x > 1$$
D. $$\displaystyle \frac{ \cos(x-1) -1 }{ x^{2} }$$ when $$x > 1$$
