To find \( f(2x + 1) \) for \( x = 2 \), we first need to substitute \( x = 2 \) into \( 2x + 1 \) and then evaluate \( f \) at that new value.

  1. Calculate \( 2x + 1 \) for \( x = 2 \): \[ 2(2) + 1 = 4 + 1 = 5 \]

  2. Now, evaluate \( f(5) \) using the function \( f(x) = x^2 + 9 \): \[ f(5) = 5^2 + 9 = 25 + 9 = 34 \]

Thus, the correct transformation \( f(2x + 1) \) for \( x = 2 \) gives the result of \( 34 \). The answer is:
