Math functions are rules that map each input from a set (domain) to exactly one output in another set (codomain), like a machine that takes an 'x' and gives one 'f(x)' (e.g.,&#13;
&#13;
f(x)=x2f of x equals x squared&#13;

𝑓(𝑥)=𝑥2&#13;

). Key types include linear, polynomial, and trigonometric functions, essential for modeling relationships in algebra, calculus, and science, represented as&#13;
