Question

Is the square root of x-3 a one to one function?

I believe it is, but I'm unsure.

Answer 1

Yes, it is. It passes the horizontal line test.

Answer 2

Thank you!

Answer 3

yes

suppose \(\sqrt{x-3}=\sqrt{y-3}\implies x-3=y-3\implies x=y\)

Answer 4

No two values of x gives the same y value. Therefore, it is a one-to-one function.

You are welcome.
