**True or False Questions with Justification**

When answering these questions, you must provide justification to receive any credit. Justification should include mathematical explanations or examples that illustrate your response.

1. **Answer each of the following as True or False and provide justification for your answer. Simply stating True or False without justification will receive no credit.**

   (a) If \( f_x (x_0, y_0) = f_y (x_0, y_0) \), then \( D_{\vec{u}} f (x_0, y_0) = f_x (x_0, y_0) (a + b) \) for unit vector \( \vec{u} = \langle a, b \rangle \)?
