Applying Function Notation (VCE SSCE Mathematical Methods): Flashcards

Systematic, formal way to identify inputs and outputs

Input values that make sense in real-world context

Negative lengths, time periods, or populations

$V(r) = \frac{4}{3}\pi r^3$

$(0, \infty)$ - all positive real numbers

$f(x) = ax + b$

Use two known points to form simultaneous equations

$f(x) = k(x - p)(x - q)$

When you know the zeros of the function

Mathematical broader; practical restricted by real-world context
