What is direction of horizontal translation?Show answer
$(x - 3)$ shifts right, $(x + 3)$ shifts left.
What is mixing up horizontal and vertical dilation factors?Show answer
$y = 2f(x)$ doubles $y$-values; $y = f(2x)$ halves $x$-values.
What is forgetting that reflection is a special case of dilation?Show answer
$a = -1$ is a reflection in the $x$-axis with no scaling.
What is order matters?Show answer
Apply transformations consistently; the standard order is inside-out within the function and then outside-in.
