Step 1:

(1)

The duty is

.

You are watching: Use the given graph of f(x) = x to find a number δ such that if |x − 4| < δ then x − 2 < 0.4.

Find

such that
whenever
.

Definition of limit:

Let

be a role defined ~ above an open interval containing
and also let
be a genuine number.

The declare

means that for every

, there exists a
such the

We need to create a connection between

and
.

Consider

.

Solve the inequality.

Subtract

from each side.

Since

,

Compare the above with
