So if we want to determine if this is going to be a want one function, um, I would say probably the most straightforward way of doing At least this one is just going by the definition and showing how this contradicts it. Well, since this is just constantly just the function, why is equal to five? Or at least I believe it was five? Yeah, So this is just above X is equal to five. So notice how it doesn't matter what we plug in for a or B, you would have like FM. Negative one is equal to five FM. Negative two is equal to five and pretty much any other number you want. So these are equal, but negative one is not equal to negative two, which would imply not one toe one. So, I mean, that's one way you go about doing it. I guess you could also apply the horizontal line test because essentially, this is just a horizontal line in itself is well, so this would also fell the horizontal line test. Um, but I think just using the definition and getting a contradiction from it is probably the most straightforward way of doing it here.
