Which exponential function shows growth f (x) = 2 (.5) x f (x) = 2 (3) x f (x) =.5 (.03) x f (x) = 3 (.8) x

For this case we have functions of the form:

y = A * (b) ^ x

Where,

A: initial amount

b: rate of change

x: independent variable

We have two cases:

b <1: the function decreases

b> 1: the function grows.

The function that shows growth for this case is:

f (x) = 2 (3) ^ x

Answer:

f (x) = 2 (3) ^ x
