Topic Notes
Do you know how to sketch and state transformations of exponential functions graphs? How about applying transformations to exponential functions including, horizontal shift, vertical shift, horizontal expansion/compression, vertical expansion/compression, reflection and inverse? You will learn them all in this lesson!
$y=a \cdot c^{b(x-h)}+k$
$a =$ vertical expansion/compression
$b =$ horizontal expansion /compression
$h =$ horizontal translation
$k =$ vertical translation
• Reflection?
