Decide whether the function is an exponential growth or exponential decay function, and find the constant percentage rate of growth or decay. f(x) = 2060 ⋅ 0.9906x

exponential growth function; 0.0094%

exponential decay function; -0.94%

exponential decay function; 0.0094%

exponential growth function; -0.94%

Exponential decay function; -0.94%

Step-by-step explanation:

we have

This is a exponential function of the form

where

a is the initial value or the y-intercept

b is the base of the exponential function

If b > 1 we have a exponential growth function

If b < 1 we have a exponential decay function

r is the percentage rate of change

b=(1+r)

In this problem we have

----> is a exponential decay function

Convert to percentage

therefore

Exponential decay function; -0.94%                          

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5
