Question

Can someone answer this for me. My teacher gave me this As a Hint so once I get this I’m good plz help

To find the decay factor, b,
find the ratio of the
consecutive y-
values between the
points (0,16) and (1.12)?

Answer 1

b = 4/3

Explanation:

In an exponential equation:

f(x) = a (b)ˣ

Evaluated at x+1:

f(x+1) = a (b)ˣ⁺¹

The ratio between them is:

f(x+1) / f(x)

= (a (b)ˣ⁺¹) / (a (b)ˣ)

= b

So the decay factor b can be found by dividing the consecutive y values.

b = 16 / 12

b = 4/3
