first of all i dont know anything about this epsilon and delta method.explain this a bit.(adsbygoogle = window.adsbygoogle || []).push({});

secondly i have been given a problem involving this method:

f(x)=x^2

given: limit x-->2 [x^2] = 4

a) what is the value of x' such that f(x')= 4 + .01? find [itex]\delta[/itex]=x'-2

b) what is the value of x[itex]_{2}[/itex] such that f(x[itex]_{2}[/itex])=4- .01? find [itex]\delta_{2}[/itex]=2-x[itex]_{2}[/itex]

and finally from both of the values of delta prove that limit is equal to 4 at x->2

i dont understand where to start.guide me
