Domain of the function

f(x)=\left[\log _{10}\left(\frac{5 x-x^{2}}{4}\right)\right]^{1 / 2}

View answer and explanation

Correct option: B

1 \leq x \leq 4

Option B (1 ≤ x ≤ 4) is correct because the domain requires the argument of the logarithm to be positive and the logarithm itself to be non-negative.
