Question 1: Select all that apply

For a soft-margin SVM with dual variables $0 \le \alpha_i \le C$ and decision function $f$ , the optimality (KKT) conditions link each $\alpha_i$ to the functional margin $y_i f(x_i)$ . Which statements follow from them? Select all that apply.

If $\alpha_i = 0$ , then $y_i f(x_i) \ge 1$ 1
If $y_i f(x_i) > 1$ , then $\alpha_i = C$ 2
If $\alpha_i = C$ , then $x_i$ is misclassified3
If $0 < \alpha_i < C$ , then $y_i f(x_i) = 1$ 4
