Summary (Grade 10 NSC Matric Mathematics): Flashcards

Mathematical relationship connecting x (input) to y (output)

Input value (x) that can be chosen freely

Output value (y) that depends on the input x

All possible x-values (inputs) for the function

All possible y-values the function can produce

Line a function approaches but never touches or crosses

$y = ax + q$ where a = gradient, q = y-intercept

$y = ax^2 + q$ creates U-shaped parabola curves

$y = \frac{a}{x} + q$ undefined at x=0, has asymptotes

$y = ab^x + q$ shows rapid growth or decay
