Question

The following relation defines y as a one-to-one function of x x y3.0 7.45-8.4 -8.072.4 -9.16-1.5 7.45TrueFalse

Answer 1

One-to-one functions are the ones that each value of "y" is related to only one value of "x". So we need to check in the provided values if that applies.

We have a group of 4 different values of "y". For these the value y = 7.45 is related to the x values of 3 and -1.5, therefore it is not a one-to-one function.
