## Homework Statement

Let a rep. any real number greater than 0

Prove that the limit as x->a of sqrt(x) = sqrt(a)

I hav to prove the above equation using using an Epsilon-Delta proof but I am not sure how to start it off.

**2. The attempt at a solution**

I assumed that if 0<|x-a|<d

then |f(x) - f(a)|

= |sqrt(x) - sqrt(a)|

I am allowed to use basic manipulations of numbers that preserved the equation and also make helper assumption values for delta if needed as long as i account for them in my proof.

I've been stuck on this question for 3-1/2 hours now so I would really appreciate any help!
