Prove that the function f(x) = 1/2+x is continuous at x=0.

I have attached the solution. My question is why are they choosing between minimum of epsilon and 1 for the value of delta epsilon?

Any help would be appreciated.

Thanks

The reason is contained in the next line after the part you underlined.

It makes the setup happen.
