They don’t have any more information available than when receiving 1 input, so they actually have to give the same outputs as one of the functions that takes only 1 input. There are only 4 binary functions of 1 input: one, zero, not, identity which correspond to the 4 possible truth tables for a function with 1 input (10, 11, 00, 01 are the only 4 options). (The one and zero functions don’t actually need any input because the output is the same regardless of the input.)

Oh and if you understand then label which are which. For {or, and, xor, implies} label each one with one of {one, zero, not, identity} for how it behaves when given 2 of the same input.
