WebThe strictest definition of a limit is as follows: Say Aₓ is a series. If there exists a real number L that for any positive value Ԑ (epsilon), no matter how small, there exists a natural number X, such that { Aₓ - L < Ԑ, as long as x > X }, then we say A is limited by L, or L is the limit of A, written as lim (x→∞) A = L. WebJan 2, 2024 · We write the equation of a limit as lim x → af(x) = L. This notation indicates that as x approaches a both from the left of x = a and the right of x = a, the output value approaches L. Consider the function f(x) = x2 − 6x − 7 x − 7. We can factor the function in Equation 12.1.1 as shown.
