Limits

Limit Rule [Constant]: $\displaystyle \lim_{x \to c} b = b$

Definition of a Derivative: $\displaystyle f'(x) = \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}$

Step-by-step explanation:

Step 1: Define

Identify

f(x) = 2x - 5

Step 2: Differentiate

[Limit] Substitute in x [Function f(x)]: $\displaystyle \lim_{\triangle x \to 0} \frac{[2(x + \triangle x) + 5] - f(x)}{\triangle x}$ [Limit] Substitute in function: $\displaystyle \lim_{\triangle x \to 0} \frac{[2(x + \triangle x) + 5] - (2x + 5)}{\triangle x}$ [Distributive Property] Distribute 2: $\displaystyle \lim_{\triangle x \to 0} \frac{[2x + 2\triangle x + 5] - (2x + 5)}{\triangle x}$ [Distributive Property] Distribute negative: $\displaystyle \lim_{\triangle x \to 0} \frac{2x + 2\triangle x + 5 - 2x - 5}{\triangle x}$ [Subtraction] Combine like terms: $\displaystyle \lim_{\triangle x \to 0} \frac{2\triangle x}{\triangle x}$ [Division] Simplify: $\displaystyle \lim_{\triangle x \to 0} 2$ Evaluate limit [Limit Rule - Constant]: $\displaystyle 2$
