Find first deriative 

### Mathematical Functions

#### Function d)
The function \( f(x) = \ln(e^x - 3x) \) represents a composite function involving the natural logarithm. Here, \( \ln \) denotes the natural logarithm, \( e^x \) represents the exponential function, and \( 3x \) is a linear component subtracted from the exponential part. The expression inside the logarithm, \( e^x - 3x \), must be positive, as the logarithm is only defined for positive values.

#### Function e)
The function \( f(x) = e^{x^2 \ln x - \frac{x^2}{2}} \) is a more complex expression. It includes:
- The exponential base \( e \) raised to the power of an expression.
- The expression \( x^2 \ln x \) which combines a quadratic term with the natural logarithm of \( x \).
- A subtractive quadratic term \( \frac{x^2}{2} \) is also part of the exponent.

Understanding these functions requires familiarity with concepts such as exponential functions, natural logarithms, and the rules governing these operations.
