I am given

f(x) = sq root x

Xo= 1

L=1

E= 1/4

y= sq root x

and it says

find a delta > 0 that for all x 0< abs value x-Xo < alpha -> abs value f(x)-L < E

I know on the right side I will have sq root x - 1 < 1/4

I am not sure what I put on the left side however. I know what Xo is but what about the x and the alpha?

I am so confused
