In Problems 7鈥� 42, find each limit algebraically

limx鈫�4x

Short Answer

Expert verified

The value of the limitlimx鈫�4x=4

Step by step solution

01

Step 1. Given Information

The limit of a function is given aslimx鈫�4x

We need to find the value of the limit.

02

Step 2. The value of the limit

We know,

limx鈫�cf(x)=limx鈫�cx=c

where f(x)=xcalled an identity function.

Therefore,

limx鈫�4x=4.
