EXAMPLE BY MS. MOODIE
Exponential Graphs
Parent Function: y = ab(x-h) +k
Parent Functiony = ab(x-h) +k
Shrink / Stretch
a
a > 1Stretch
0< a < 1Shrink
Horizontal Translation
h
h >0Right
h < 0Left
Vertical Translation
k
k > 0Up
k < 0Left
Note: the function states (x-h) so the translation will appear to be moving in the opposite direction of what would seem intuitive.
Stretch: y = 2x Stretch: y = ½x
Stretch / Shrink
Right: y = 3(x-5) Left: y = 3(x+5)
Horizontal Translation
Up: y = 3x +5 Down: y = 3x - 5
Vertical Translation
y = 2(x-5) +5 y = ½(x+5) - 5
Composite Function
ExtraCredit
If you wish to receive 5 points of extra credit on your final presentation, you may embed a video that is related to the type of function you are graphing.
You may find a video online or you may create your own, the choice is yours.
