G= {(1, 1), (1, 2), (1, 3), (1, 4); is g a function and why?

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
