For the function f(x) = 2. Find lim(x to...

For the function `f(x) = 2`. Find `lim_(x to 1) f(x)`

Text Solution

Verified by Experts

f(X) = 2, being a constant function takes the same value i.e., 2 in every case i.e., if we take the value of f(x) when x approaches 1 either from left or right, it will be equal to 2.
`underset(x to 1)(lim) f(x) = underset(x to 1^(+))(lim) f(x) = underset(x to 1)(lim) f(x) = 2`
Graph of the function f(x) = 2 is the line parallel to x-axis and is shown below:

So, from graph also it is clear that the required limit is 2.
