AlglB GRAPHING Exponential Functions Name Dorr c / Scott y = ab* a: initial amount; b: growth or decay factor hour y Exponential GROWTH y = ab* y = a(1 + r ) * F is the rate, as a decimal in the equation #1 y = 3* # 2 = 2+ 2x 43 y = 4. 2X initial amount, a : initial amount, a : X initial amount, a : X growth factor, b : growth factor, b : x domain: growth factor, b : X range: domain: () range: ( -8, 8)9ly. Exponential DECAY y = ab* y = a(1 - r)* r is the rate, as a decimal in the equation 1) y = 12(=)* 2) y = 12(=)* 3) y = 6( -)* -10 a: 12 b: = decay factor a: X b: X ": X2 b: V decay rate 1-r= .25 1= * = 12 Y = 4 domain: ( - 8, 8), X 1xee) 2x range: (01 8 )
