(A) Given function is $f(x) = x^{2} - 2x$. To find the interval where the function is strictly decreasing,we first find the derivative $f'(x)$. $f'(x) = \frac{d}{dx}(x^{2} - 2x) = 2x - 2$. $A$ function is strictly decreasing when $f'(x) So,$2x - 2 $2(x - 1) $x - 1 $x Thus,the function $f(x)$ is strictly decreasing in the interval $(-\infty, 1)$.
