Given an expression like $|x - a|$, its piecewise form is: $$ |x - a| = \begin{cases} x - a, & \text{if } x \geq a \\ -(x - a), & \text{if } x < a \end{cases} $$ --- Example Rewrit…

The easiest way to evaluate a limit is to directly plug in the value of $x$. Example: $$ \lim{x \to 1} (3x + 2) $$ - Plug in $x = 1$: $3(1) + 2 = 5$ Since there's no division by ze…

When direct substitution leads to an indeterminate form like $\frac{0}{0}$, simplify the expression algebraically. Example: $$ \lim{x \to 3} \frac{x^2 - 9}{x - 3} $$ Steps: 1. Fact…

The absolute value of a number represents its distance from 0 on the number line, regardless of direction. It is defined piecewise as: $$ |x| = \begin{cases} x, & \text{if } x \geq…

Function notation is a shorthand way to describe how a function maps inputs to outputs. The expression $f(x)$ means "the value of the function $f$ when the input is $x$." It's a mo…

When evaluating a limit like $\frac{x^3 - a^3}{x - a}$, use the difference of cubes identity: $$ x^3 - a^3 = (x - a)(x^2 + ax + a^2) $$ Example: $$ \lim{x \to 2} \frac{x^3 - 8}{x -…
