To analyze the function \( f(x) = \sin(23x) \) in relation to its parent function \( g(x) = \sin(x) \), we need to examine the effect of the coefficient 23 in front of \( x \).

The coefficient inside the sine function indicates a horizontal transformation:

  • A coefficient greater than 1 (like 23) results in a horizontal compression.
  • This compression factor is the reciprocal of the coefficient, thus it becomes \( \frac{1}{23} \).

Therefore, the graph of \( f(x) = \sin(23x) \) can be described as:

The graph is a horizontal compression by a factor of \( \frac{1}{23} \).

However, since "by a factor of \( \frac{1}{23} \)" is not one of the options provided, we would select the closest statement regarding the transformation:

The graph is a horizontal compression by a factor of 23.
