Use this for “Which change is f(x − 3), and which is f(x) − 3?”
Sort
What does the change do to the graph of y = f(x)?
Tap a card, then tap its group.
Assumptions
•
A number added inside the brackets acts on x: it moves the graph sideways, opposite to its sign.
•
A change outside acts on y, the way it reads: + 4 moves the graph up 4.
•
A minus sign reflects: −f(x) across the x-axis, f(−x) across the y-axis.
