WebWith limits, since you often have them diverge toward +∞ or −∞ or else tend toward 0, you can save yourself unnecessary work by not simplifying any constants until you know you don't have an infinity or zero situation. When tending toward 0, your constant is irrelevant and there is no need to simplify. 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.
