Answer
limit of a constant is equal to the constant. So,
$\lim\limits_{x \to 2}$ -1 = -1
Work Step by Step
limit of a constant is equal to the constant. So,
$\lim\limits_{x \to 2}$ -1 = -1
Proof using epsilon and delta:
given function is constant.So, for any value of x, f(x) = -1. It is just a horizontal line given by y = -1. So, for any value 'c' that x is going to approach, value of function f(x) will be -1 so, we can set epsilon = 0 and so is the delta = 0.
