Hello. Today we're gonna be identifying whether the given function is 1-1. So in order to verify whether a function is 1-1, we're going to plug in some arbitrary constant A into our function. And we're gonna set that equal to B plugged into our equation. So we're going to create this equation F of A is equal to F of B. And if we can simplify this to give us A is equal to B, then that verifies that the given equation or the given function is going to be 1-1. So the function given to us is Y is equal to 5 X -13. If we plug an A to this given function, we get five, a -13. And if we plug in B into the given function, we get 5B -13. So what I've created here is the F of A is equal to F F B equation. And now we want to go ahead and try to simplify this to give us A is equal to B. So the first thing we can go ahead and do is add 13 to both sides of the equation. That is going to leave us with 5 a is equal to five B. And in order to get rid of the five coefficient, we can divide both sides of the equation by five. And that is going to leave us with A S equal to B which verifies that the given function is 1 to 1. And with that being said, the answer to this problem is going to be a. So I hope this video helps you in understanding how to approach this problem. And I'll go ahead and see you all in the next video.
