Graphing Exponential Growth/Decay
GRAPHING EXPONENTIAL GROWTH/DECAY:
y= aŸbx-h+k
a= multiplier
a>1 = stretch 0<a<1 = compression
a<0 (negative) = flipped over x-axis
b= base
b>1 = GROWTH (always increasing)
0<b<1 = DECAY (always decreasing)
h= left/right (opposite)
k= up/down
Domain
(-∞,∞) = All Real numbers
Range: y>k (Positive)
y<k (Negative)
Asymptote
y=k
