Summary (Grade 12 NSC Matric Mathematics): Flashcards

Rule that gives exactly one output for each input

Determines if a graph represents a function

Undoes what the original function does

$y = x$

Function's domain becomes inverse's range (and vice versa)

$y = ax + q$

$y = b^x$ where $b > 0$ and $b \neq 1$

$y = \log_b x$

$\log_a x^b = b \log_a x$

$\log_a xy = \log_a x + \log_a y$
