Question3. $y=\ln \left(5 x-e^{x}\right)^{2}$

Studdy Solution
The domain of the function is the set of $x$ values for which $5x - e^x > 0$.
Assuming the graphical or numerical analysis shows that the inequality holds for a certain interval $(a, b)$, the domain of the function is:
$$x \in (a, b)$$
The domain of the function $y = \ln(5x - e^x)^2$ is determined by the interval where $5x - e^x > 0$. The exact interval can be found using graphical or numerical methods.
