Asurvey reveals that the sales of smartphones is increasing considerably. the average annual sales of smartphones, in million units, n years after the survey is conducted is modeled by function p below. the parameter b is an unknown positive base.

when the survey was initially conducted the average sales of smartphones was 1.7 million units

Step-by-step explanation:

The average annual sales of smartphones is given by function

Exponential growth function is given by

Where a= initial value

b = growth factor , b= 1+r where 'r' is the growth rate

x is the time period

Now we compare f(x) with P(n)

the value of a= 1.7 that is the initial value.

So we can say, when the survey was initially conducted the average sales of smartphones was 1.7 million units
