  1. A: y = 4 - |x-8|

    B:
    y = x-7
    y = 7 - |x-14|

    C: one of the domain values must map to 2 range values. Not a function.

    D: tricky, if you want f=g only for rational numbers. If f and g are continuous, then f=g for all reals.

    E: y = ⌊x⌋ where ⌊x⌋ is the greatest integer less than or equal to x. Equivalent to x-mod(x,1)
