Question

Each of the functions below model the monetary value of an item. Which is the only

that has a growth factor showing the item is increasing in value?

O a(x) = 90(3/4)^x

B(x) = 215(5/4)^x

c(x) = 73(0.98)^x

d(x) = 12(0.24)^x

Answer:The correct answer is .

Step-by-step explanation:We must remember that each option represents a geometrical progression, whose model is represented by:

Where:

– Dependent variable, dimensionless.

– Initial value, dimensionless.

– Common ration, dimensionless.

A geometric function is decreasing and monotone when , stable when and increasing and divergent when .

The equation is the only one that is increasing in value, as notice that . Therefore, the correct answer is B.
