Question

Find an open interval about c on which the inequlity |f(x)-L| < ε holds. Then give a value for δ > 0.

f(x) = x+1
L=5
c=4
ε=0.01

Answer 1

plug the values of epsilon and L for the interval values, the difference between the mid point of this range and either of the limits of the region would give you delta.
