Question
Use the precise definition of limit, without using any of the limit laws, to prove that
lim /2x + 10 = 4.
x→3
Hint: Given an arbitrary ɛ > 0, you need to explicitly find a 8 > 0 , in terms of ɛ, and then prove that for your
choice of 8 > 0, you always have V2x + 10 – 4| < ɛ whenever |x – 3| < 8.
