Combination of Graphs (Junior Cert Mathematics): Flashcards

Functions have same value at certain points

Where two graphs cross each other

Parabola

Same output for same input ($x$-value)

Look for points where graphs cross

$f(x)$ graph is below $g(x)$ graph

Outputs of $f(x)$ are smaller than $g(x)$

Range of $x$-values between intersection points

Visual representation makes relationships clear

Can quickly spot where graphs cross or overlap
