From the graph of f, state each x-value at which f is discontinuous. For each x-value, determine whether f is continuous from the right, or from the left, or neither. (Enter your answers from smallest to largest.) x = (smallest value) continuous from the right continuous from the left neither x = continuous from the right continuous from the left neither x = continuous from the right continuous from the left neither x = (largest value) continuous from the right continuous from the left neither
