(C) For the function $y = \sqrt{\log _{10} \frac{3x - x^2}{2}}$ to be defined,the expression inside the square root must be non-negative: $\log _{10} \left( \frac{3x - x^2}{2} \right) \geq 0$ Since $\log _{10} 1 = 0$,we have: $\frac{3x - x^2}{2} \geq 1$ $3x - x^2 \geq 2$ $x^2 - 3x + 2 \leq 0$ $(x - 1)(x - 2) \leq 0$ This inequality holds for $x \in [1, 2]$. Additionally,the argument of the logarithm must be positive: $\frac{3x - x^2}{2} > 0$ $x(3 - x) > 0$ $x(x - 3) This holds for $x \in (0, 3)$. The intersection of $x \in [1, 2]$ and $x \in (0, 3)$ is $x \in [1, 2]$.
