![\lim_(x\rightarrow \infty)C=C](https://img.qammunity.org/2020/formulas/mathematics/college/2ckmb9wwg4ja8tbrmgtczkgplp2sj4snj2.png)
Explanation:
We are given that f(x)=c=Constant for all x in R
We have to find that why f(x) not equal to zero when x approaches to zero.
![\lim_(x\rightarrow \infty)f(x)](https://img.qammunity.org/2020/formulas/mathematics/college/dwrxrcdmm7t932fijdmp2136c5072xi72c.png)
not equal to zero
We are given that function which is constant for all x in R.
When x approaches then the value of function does not change. it remain same for all x in R because function is constant.
Hence, when x tends to infinity then f(x) is not equal to zero.
