Question
For the following graph of \( f(x) \), identify where \( f(x) \) is not differentiable and why.

**Graph Explanation:**

The graph shows a function \( f(x) \) plotted in the Cartesian plane with the x-axis ranging from -5 to 5 and the y-axis from -4 to 4. The function appears to approach the y-axis but is not defined at \( x = 0 \), as there is a gap indicating a discontinuity. The curve on the left approaches \( x = 0 \) from the negative side, moving downwards and sharply turning upwards as it approaches zero. From the positive side, the function approaches zero from above. This indicates a discontinuity at \( x = 0 \).

**Options:**

- \( \circ \) \( f(x) \) is not differentiable at \( x = 0 \) because \( f(x) \) is not defined at \( x = 0 \).

- \( \circ \) \( f(x) \) is not differentiable at \( x = 0 \) because \( f(x) \) has a corner at \( x = 0 \).

- \( \circ \) \( f(x) \) is not differentiable at \( x = 0 \) because \( f(x) \) has a cusp at \( x = 0 \).

- \( \circ \) \( f(x) \) is not differentiable at \( x = 0 \) because \( f(x) \) has a jump at \( x = 0 \).
