2.2 THE LIMIT OF A FUNCTION

Notes go here for 2.2... example:
Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle \lim_{z\to z} [f(x) g(x]) = c \cdot[ \lim_{x\to a} f(x) ] }

2.3 CALCULATING LIMITS USING THE LIMIT LAWS

$\lim _{x\to a}=c\cdot [\lim _{x\to a}f(x)]$

2.6 LIMITS AT INFINITY; HORIZONTAL ASYMPTOTES

Horizontal Asymptote or H.A

This ultimately means that the equation will APPROACH TO ONE it will not ever be on one.

V.A or a vertical asymptote is when the function becomes infinity such as Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle \lim_{x \to c}f(x)=\infty}

2.7 DERIVATIVES AND RATES OF CHANGE

We later apply the points on which we want to find the slope.
