What is the domain of the following relation? Is it a function? R: {(1,2), (2,2), (-1, -2), (-3, 4)} a) {-2, 2, 4} not a function because output values are not repeating
b) {-3,-1, 1, 2} not a function because the input values are not repeating
c) {-3,-1, 1, 2} is a function because there are no repeating input values
d) {-2, 2, 4} is a function because there are repeating output values
can someone pls help me??
