Domain and range of 1/x-7 ?

Domain: All real numbers x such that x ≠ 7. Or you can write it as (-∞, 7) U (7, ∞)

Range: All real numbers y such that y ≠ 0. Or you can write it as (-∞, 0) U (0, ∞)

Domain For 1

R-0 Domain Function does not exist at x=0

R range

Domain: All genuine numbers x this kind of that x ≠ Seven- Or you are able to create it as (-∞, Seven- U (7, ∞) Range: All genuine numbers y this kind of that y ≠ 0. Or you are able to create it as (-∞, 0) U (0, ∞)
