Graphing Exponential Growth/Decay

Graphing Exponential Growth/Decay

1. Create the Parent Graph.
2. Identify A,H,K.
3. Create your new T-Chart.

Domain: All real #'s.
Range: y>k; when a is positive. y<k; when a is negative.
Asymptote: y=k.
4. Draw Asymptote.
5. Graph new points.
Exponential Formula:  y=a×bx-h+k
a = multiplier.
a>1 = stretch
0<a<1 = compression
a< 0(negative) = flipped over x-axis.
b = base
b>1 = whole #, growth, always increasing.
0<b<1 = fraction; decay, always decreasing.
B is never negative only the multiplier is.
h = lf/rt; opposite
k = up/dn
