Recognising Relationships (VCE SSCE Mathematical Methods): Flashcards

Understanding variable relationships using graphs

Graph slopes upward (left to right)

Graph slopes downward (left to right)

Horizontal line, $y$ constant as $x$ changes

Linear (equal volume = equal height increases)

Large increases initially, smaller increases later

Describe where rate of change is positive/negative/zero

Connects separate intervals

Zero (transitions positive to negative or vice versa)

Understand form & behaviour without algebraic formula
