Find the limit: lim x → 1 ( 2 x + 4 ) .

To determine

To calculate: The value of limx1(2x+4).

Explanation

Given information:

The provided limit is,

limx1(2x+4)

Formula used:

Notation for a limit:

limxcf(x)=L

The above expression is represented as, “the limit of f(x) as x approaches c is L.”

Calculation:

Consider the function f(x)=2x+4,

In order to draw the graph first create a table as,

 x 0.9 0.99 0.999 1 1.001 1.01 1.1 f(x)=2x+4 5.8 5.98 5.998 6 6.002 6.02 6.2

From the table it is clear that the x approaches the 1 the function f(x) approaches to 6
