TermDefinition
Vertical Stretch/Shrink occurs when a function is multiplied by a constant, a. If a is between 0 and 1, there is a vertical shrink (or compression). If a is greater than 1, there is a vertical stretch. Both by a factor of a.
Horizontal Stretch/Shrink occurs when a function's input is multiplied by a constant, b. If b is between 0 and 1, there is a horizontal stretch by a factor of 1/b. If b is greater than 1, there is a horizontal shrink (or compression) by a factor of 1/b.
Horizontal translation left/right occurs when a constant is added to or subtracted from a function's input. Adding a constant = translation left; Subtracting a constant = translation right.
Vertical translation up/down occurs when a constant is added to or subtracted from a function. Adding = translation up; Subtracting = translation down.
Reflection across x-axis: occurs when a function is multiplied by a negative coefficient.
Reflection across y-axis occurs when a function's INPUT is multiplied by a negative coefficient.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
