Applying Function Notation (VCE SSCE Mathematical Methods): Quizzes

Input values that make sense in context

$(0, \infty)$

They don't make sense in real contexts

Simultaneous equations

$3$

$-\frac{4}{3}$

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

$-2$

Expanding too early instead of using factored form

Clearly label equations before solving
