Question

Identify each function modeling either as exponential Growth or exponential Decay.

1) y = 0.65(1.3)x

2) y = f(x) = 2(0.65) x

3) s(t) = 0.8(1/8)x

4) y = 12(1.7)x

5) y = 5(6)x

6) y = 5/6(0.45)x

Answer 1

to identify growth/decay = look at the value in parenthesis.
if >1 this is growth
if <1 this is decay
